“If I had undeniable evidence for God, I wouldn't be an atheist, now would I?” Francesco Cimmarrusti

This gentleman has highlighted the issue with atheism. They have undeniable evidence, and yet they still profess the foolishness of atheism. There’s a reason for that. First, here’s the undeniable evidence:

1. Creation: The incredible order of Nature, from the atom to the universe. It is scientifically impossible for Nature to have made itself, and it is also scientifically impossible for it to be eternal. There had to be an uncreated First Cause.
2. Conscience: The existence of the God-given, society-shaped conscience. The conscience (“with” “knowledge”) intuitively tells us that we are moral beings, separate from the animals, and therefore responsible to God.
3. Commandments: Our conscience (the “work of the Law” written on our hearts) independent of our will tells us that we have violated the Ten Commandments—showing us that we are sinners, heading for Hell.
4. Conversion: In a moment of time any “atheist” can come to know the God he only knows about, by obeying the gospel. But they refuse to because they love their sin.
