Jesus said, “…for this reason I was born, and for this I came into the world, to testify to the truth. Everyone on the side of truth listens to me.” (John 18:37)
Have you ever heard someone say, “You’ve got your own truth about God, and I’ve got mine”? The inference is that two contradictory opinions (and in reality, billions, if we include everybody else on the planet) can both be true at the same time. While it may seem a polite statement, unfortunately, it’s totally illogical.
Truth is not subjective but absolute.
For example, the truth is gravity exists, and I am subject to it whether I believe in it or not. I cannot “create” my own “truth” by what I believe. I cannot, through my belief that gravity does not exist, create and live in my own little universe devoid of gravity.
This same principle applies to God and morality. We have the freedom to believe or to not believe in God and we have the freedom to believe or to not believe that homosexuality is immoral, but we cannot, through our own personal belief, “create” a “truth” to which we are absolutely subject.
Our personal beliefs cannot negate our absolute subjectivity to the absolute truth.
Just as we are all subject to gravity, so also we are all subject to the one, absolute truth about God whether we believe in it or not.
God has revealed the absolute truth to us through the Bible and the Person of Jesus Christ.
Anyone can make this claim, just as I am now, but how can we know for certain it is the absolute truth? God has proven his testimony to us by doing something only God can do: Fulfilling Bible prophecy.
In the Bible, YHWH, the God of Israel, the God incarnate in the Person of Jesus Christ, sets forth this challenge to all other alleged gods (and to all the people who believe in them and worship them):
“‘Present your case,’ says the LORD. ‘Set forth your arguments,’ says Jacob’s King. ‘Tell us, you idols, what is going to happen. Tell us what the former things were, so that we may consider them and know their final outcome. Or declare to us the things to come, tell us what the future holds, so we may know that you are gods. Do something, whether good or bad, so that we will be dismayed and filled with fear. But you are less than nothing and your works are utterly worthless; whoever chooses you is detestable.” (Isaiah 41:21-24)
God filled the Bible with hundreds of prophecies, and then he fulfilled them through the course of history. One of the primary reasons why he did this was to demonstrate to us that he is God. This issue is covered further in 8) Can Bible Prophecy be Proven?
