And the rest of the New Testament expands on how this truth affects our lives. So the Bible gives us an objective revelation of the truth about God. It is something outside of ourselves. It is the truth about God as revealed from Himself. Every other religion of the world is based upon someone's idea about God.
Many people today prefer to make their own god.
They don't want to have to accept what God has revealed about himself. They would rather pick and choose what they believe about God. That is very subjective, very relative. There are more than a thousand likenesses of Buddha, each a little different from the others. They are there so that a person can come in, find the one that looks the most like himself, and worship it.
