If there is a God, then it's likely that he can work through all religions, not just one, and even connect with people without any organized religion at all.
It's not true that there's only one way to God and that all other religion are false. That's what exclusive narrow minded religionists and fundamentalists want you to believe, not what God wants you to believe. Here are some good logical reasons why Jesus and the Bible are NOT the "only way to God".
1) First, think about this: The creator (or creators) of this world created a lot of VARIETY in it. He or she (or they) made many different types of plants, animals, nature, vegetables, colors, flavors, flowers, climates, marine life, mammals, human races, etc. So obviously the creator LOVES variety. Even Christian Creationists admit that "God loves variety". So why then would God suddenly become so narrow minded when it comes to ways to reach him? Why would he only make one religion true while all the rest false? A creator of the universe would not be that closed minded or exclusive, especially if he loves variety and created a lot of it. It would be inconsistent with his love for variety and diversity. That would be like a creator who created many different cultures and races, but saying that only one of them was good, while all the others bad. We all know how absurd that would be. Logically speaking, a being or entity who cherishes and loves variety would not be so exclusive and narrow minded as to only allow one religion to be "the only right way" and all others to be "the wrong way" and condemn everyone who follows them. That would be far too inconsistent and out of line with his own character.
2) Second, you would think that a creator of the universe would be broad minded, not narrow minded, as well as fair and reasonable, since his mind and perception are so far above ours, and his wisdom so vastly superior to ours, just as our mind is to an insect's mind. Such a broad minded creator would not send the followers of only one religion to heaven while sending the rest to hell. Anyone that trite and small minded would not even be smart enough or capable of creating the universe or even our planet in the first place. Instead, he would be like a hick living in a shack and achieve nothing due to his small mindedness.
3) Third, why would a powerful creator limit himself by only working through one religion? An omnipotent and omniscient God ought to be able to transcend such narrow man made limitations. If he only accepted those of one religion, then he would be rejecting billions of people in other religions and missing out on them. He'd be alienating billions of his own children.
Consider this: If your father or mother asked you to visit them, would they mind if you took a car to see them, a bus, a plane, a helicopter, a boat, a parachute, or even if you walked on foot? Obviously not, as long as you arrive and try to see them, that's what counts. Or, if they wanted you to contact them, would they mind if you called them by phone, Skyped them, emailed them, or wrote a letter to them by mail? Would they accept all those forms of contact, or only one form? I'm sure they would accept any form of contacting them. So why wouldn't God? Especially a reasonable and sane God?
The point is, if God wants to badly to reconnect with his children, why wouldn't he work with them? Heck even corporations and businesses allow you multiple ways to pay them and contact them. They take different types of credit card for payment, and also cash or check. And you can contact them by phone, email, postal mail, using their online contact forms, or sometimes even via live online chat. So if a business allows you different ways of paying or contacting them, why wouldn't God? Don't you think God would at least be as reasonable as a business would be? Think about it.
4) Fourth, how would God expect the average person to know which religion was "the true way to God" anyway? One cannot look at all the religions of the world and easily distinguish which one is true and which isn't, even if one is really smart or bright. So why would God expect that one could, when in reality one cannot? Wouldn't God have the sense to put himself in an ordinary man's shoes and realize that if he were human, he would have no idea which religion was the right way to God either? You would think that God would consider this, since a reasonable man would. Is it asking too much to expect God to have common sense and act like a reasonable man?
5) Fifth, all major religions have resulted in many stories and testimonials of changed lives, miracles and answered prayers. There are documented accounts of miracles from people of all faiths, not just Christianity. So Christians do not have a monopoly on changed lives, miracles or answered prayers. All major faiths and religions do. This indicates that some higher power or divine source (even if it's within rather than without) is at work in all of them.
6) Sixth, text in a book is not literal truth and is not infallible, but is in fact very malleable and subject to manipulation, change and alteration. They are reflections of the opinions and biases of the author. We all know that. Words are merely words. And we all know that human hands wrote the Bible, even Christians admit that. Therefore since humans are fallible and imperfect then so is the Bible. It's simple logic. Plus you don't even know who wrote the Bible and you never even met them. They are strangers to you, and we all know you can't entrust your life to a stranger you never met. Therefore, you cannot hang your whole life or a major belief on one or two Bible verses, since after all they are just mere words.
One of America's founding fathers, Thomas Paine, made this point eloquently in his book "The Age of Reason":
Paine's argument is logical. Since text is too malleable and changeable by man, the only objective universal reflection of God is his CREATION, in the world around us. This is logical, since a creator's work and creation is usually a reflection of himself, just as an artwork is usually the reflection of the mind and soul of the artist. Thus the argument makes sense and has sound logic. Therefore, from the Creator's creation in the world around us, all we can gather is that he or she (or they) must love variety and is capable of great love and beauty as well as cruelty and pain, and is both good and evil, since our world is a dualistic world of opposites. Hence we can assume that these qualities probably reflect our Creator as well. Furthermore, since our human nature contains both good and evil, positive and bad qualities, then since "man is created in the image of God", then it logically follows that our Creator possesses the same qualities too. Moreover, even mankind's reason and critical thinking (as I am applying here in my analysis) must be part of God's nature too, otherwise why would he bestow us with the ability to think and reason? That's all we can logically infer. Beyond that, all we can do is try to connect to him or her to gain more information or revelations or insights.But some, perhaps, will say: Are we to have no word of God — no revelation? I answer, Yes; there is a word of God; there is a revelation.
THE WORD OF GOD IS THE CREATION WE BEHOLD and it is in this word, which no human invention can counterfeit or alter, that God speaketh universally to man.
Human language is local and changeable, and is therefore incapable of being used as the means of unchangeable and universal information. The idea that God sent Jesus Christ to publish, as they say, the glad tidings to all nations, from one end of the earth to the other, is consistent only with the ignorance of those who knew nothing of the extent of the world, and who believed, as those world-saviours believed, and continued to believe for several centuries (and that in contradiction to the discoveries of philosophers and the experience of navigators), that the earth was flat like a trencher, and that man might walk to the end of it.
But how was Jesus Christ to make anything known to all nations? He could speak but one language which was Hebrew, and there are in the world several hundred languages. Scarcely any two nations speak the same language, or understand each other; and as to translations, every man who knows anything of languages knows that it is impossible to translate from one language to another, not only without losing a great part of the original, but frequently of mistaking the sense; and besides all this, the art of printing was wholly unknown at the time Christ lived.
It is always necessary that the means that are to accomplish any end be equal to the accomplishment of that end, or the end cannot be accomplished. It is in this that the difference between finite and infinite power and wisdom discovers itself. Man frequently fails in accomplishing his ends, from a natural inability of the power to the purpose, and frequently from the want of wisdom to apply power properly. But it is impossible for infinite power and wisdom to fail as man faileth. The means it useth are always equal to the end; but human language, more especially as there is not an universal language, is incapable of being used as an universal means of unchangeable and uniform information, and therefore it is not the means that God useth in manifesting himself universally to man.
It is only in the CREATION that all our ideas and conceptions of a word of God can unite. The Creation speaketh an universal language, independently of human speech or human language, multiplied and various as they may be. It is an ever-existing original, which every man can read. It cannot be forged; it cannot be counterfeited; it cannot be lost; it cannot be altered; it cannot be suppressed. It does not depend upon the will of man whether it shall be published or not; it publishes itself from one end of the earth to the other. It preaches to all nations and to all worlds; and this word of God reveals to man all that is necessary for man to know of God.
Do we want to contemplate his power? We see it in the immensity of the Creation. Do we want to contemplate his wisdom? We see it in the unchangeable order by which the incomprehensible whole is governed! Do we want to contemplate his munificence? We see it in the abundance with which he fills the earth. Do we want to contemplate his mercy? We see it in his not withholding that abundance even from the unthankful. In fine, do we want to know what God is? Search not the book called the Scripture, which any human hand might make, but the Scripture called the Creation.
Now of course Christian fundamentalists will cite Bible verses such as John 14:6 where Jesus says, "I am the way, the truth and the life. No one comes to the Father but by me." and 1 Timothy 2:5 that says, "For there is one God and one mediator between God and men, the man Christ Jesus." as authority to try to prove that Jesus is the only way to God. But these are just words and verses. They don't create absolute truth and they do not erase all other religions and beliefs. They are merely a few verses in a book, that's all. Not absolute literal truth or authority. So you gotta remember that:
* Words are just words. They don't create absolute reality, literal truth or law. Anyone can say anything. Text is malleable and easily subject to change and alteration. Plus they can easily be metaphorical and be the opinion and bias of the author.
* You don't know for sure that the historical Jesus even said those things. Jesus wrote nothing himself, which is strange if he had intended to start a new religion. Those words from the Gospel of John were written 50 to 70 years after Jesus lived. And anyone could have written them. You should not trust random anonymous sources, as you know. In fact, many of the Bible authors are anonymous and unidentified. So they carry little or no weight or credibility.
* Even if the historical Jesus really said those things, it doesn't mean they are literally true. No one is infallible or perfect, no matter what they say. You wouldn't believe anyone claiming to be perfect or infallible today, so why would you believe that someone was perfect and infallible 2,000 years ago? It doesn't make sense. Likewise, you wouldn't believe anyone today claiming to be "the only way to God" so why would you believe it if someone said it 2,000 years ago? It makes no sense.
* Each religion and its texts were created by man, or is man's interpretation of the divine, even if they were inspired by a divine source. Therefore, at best each religion and its texts are a mixture of both man and the divine, and are hence subject to mankind's bias, opinions, interpretations, agendas, politics, mistakes, contradictions, etc. So just because there are verses in the Gospels or Epistles that claim Jesus is "the only way" doesn't make it true. And even if higher beings or divine entities wrote the Bible, that wouldn't make them infallible. Just because something is higher or more powerful than you, doesn't make it perfect or infallible. For example, an ant may see you as big and powerful, but would it be right in assuming that you are perfect and infallible? One of the trillions of living cells in your body may see you as God, but would it be right in assuming that you are all knowing and infallible and perfect? Of course not.
* These Gospels were written as stories of "good news" and are documents of faith, and the Epistles are merely personal letters by Paul and others. They were not meant to be accurate historical records, or infallible dogma or canonical law. And even if they were, it wouldn't make them so. Just because someone "says so" doesn't make it so.
The bottom line is that words in any text form are merely words. They are not divine absolute laws that are infallible or irrefutable. They do not create reality or truth either. Words are merely words. No need to make them something they are not.
Most likely, Christian Churches like to claim that they are "the only way to God' because it gives them power, authority and exclusivity. Human nature seems to get off on that. It makes them feel more special and meaningful. But once you broaden your mind and your perspective of religions, spirituality, life, the world and reality, you begin to see that these "only way" beliefs are not true. And you realize that God and the universe are much bigger than that. As the famous spiritual teacher and author Deepak Chopra said, "Once you define God, you limit God."
What all this means is that not only can you connect with God through different religions - as long as you are sincere of course - but you can connect with God even without a religion as well. Some connect with God through Nature, as the Native American tribes did. And some through meditation (which has been dubbed "listening to God" while prayer is "talking to God") or yoga. There are those that connect with divine inspiration through art, music and poetry. Others just have a general belief in God without religion. It's a personal choice. There's no one right way. Everyone interacts with the divine differently. As the late comedian George Carlin said, "Religion is like a pair of shoes. Find one that fits, but don't try to make me wear your shoes."
In fact, God may even have many faces, as Hindus believe. Hinduism is the only religion that is both polytheistic and monotheistic. It has many deities, but all these deities are considered different faces and facets of the same God, Brahma. So it is the most complex religion that has God as multi-dimensional and multi-faceted, beyond human understanding. If this is true, then God is truly more complex than we can imagine, per the Chopra quote above.
So far, I've given a number of logical reasons above why if there's a God, he should be able to work through all religions, or no religion. In contrast, ask a Christian to give a logical reason why Jesus is the only way to God and they can't give one. All they can say is "because the Bible says so" which does NOT constitute a logical reason.
