God is a Person without form and the One who created everything. He is almighty, all-knowing, wise, loving, merciful, holy, righteous and just. If someone worships a snake or thunder as god, it is clear that he is not looking at this God. How then can people say that no matter which god anyone worships they are really calling the same God under different names? For those who think like that, God is just a concept in their mind and not a real person, and then it is not difficult to imagine that it is all right for people to have different concepts of god in their mind. For such people, one question they ask is why anyone else should bother as long as these people are happy with their concept and it satisfies their need for god!
But God is a real Person with whom we can have a real relationship. As our Creator we are accountable to Him on His terms, and it is from Him that all blessings come. We need to have the true understanding of who God is and how we can relate to Him. It's not about having any philosophy of life that satisfies our mind by providing some answers to questions that come up. Many people seem to be satisfied as long as their religious leaders give them some explanation because the people assume that these leaders know what they are talking about. But if we examine all these man-made philosophies we can see that they are not coherent in themselves and they do not provide a comprehensive explanation connecting God, man and His dealings with us. God has revealed Himself to us through time in the Bible, and what we see there is able to connect everything together in such a way that they make sense like nothing else does.
Many people, including some people who consider themselves as Christians, read and discuss different philosophies and conclude that 'this group believes like this', 'that group like that' but 'I think like this'. It doesn't seem to bother them that these concepts don't make any practical difference in the way they live daily, as long as they know how to quote great writers and teachers!
"And there is no other God besides Me, a righteous God and a Saviour; there is none except Me. Turn to Me and be saved, all the ends of the earth; for I am God, and there is no other" (Is.45:21,22). There is no one else who loved us so much that He gave Himself in order to save us from our sins (Jn.3:16). But this God is also our Judge before whom we will have to give an account for our life one day (Ro.14:12). So, each of us has to make sure that our understanding of God is right, we have a proper relationship with the true God and that our life is in line with what He wants from us.
Someone says it will be impossible to every one to go through all the different concepts of God with our limited mind and time, and find out which is right. Yes and no. If we sincerely search for the Truth, God promises He will direct our path. "You will seek Me and find Me when you search for Me with all your heart" (Je.29:13).
