What is sin?

What is sin? Sin is simply disobeying God. It's choosing your own way, instead of God's way. Since the very first sin of Adam and Eve, the first man and woman, every person is born with a sinful nature, a natural tendency toward sinning. Did you ever notice that an infant does not have to be taught how to be selfish? From our earliest beginnings, our lives center around ourselves, instead of being centered on our God, our Creator.

For all have sinned, and come short of the glory of God; Romans 3:23

If we say that we have no sin, we deceive ourselves, and the truth is not in us. 1 John 1:8

If we say that we have not sinned, we make him a liar, and his word is not in us. 1 John 1:10
