Is true in every reality.
Not conditional truth. Like this coffee is good. I look good. I feel good.
What is always true?
Time is true. Reality is true. The past is true, and always true.
But reality had a beginning. Time had a beginning. And if reality began, so did history. Therefore, they are not absolutely true. The only thing that would be true in every reality, even before time and reality is God. So not only is God true, but he is literally the only thing that is absolutely true.
I am the way and the truth and the life. No one comes to the Father except through me. -John 14:6
