Okay, let's start with Romans 1:21-25 for example
21 Because that, when they knew God, they glorified him not as God, neither were thankful; but became vain in their imaginations, and their foolish heart was darkened.
22 Professing themselves to be wise, they became fools,
23 And changed the glory of the uncorruptible God into an image made like to corruptible man, and to birds, and fourfooted beasts, and creeping things.
24 Wherefore God also gave them up to uncleanness through the lusts of their own hearts, to dishonour their own bodies between themselves:
25 Who changed the truth of God into a lie, and worshipped and served the creature more than the Creator, who is blessed for ever. Amen."
You notice that it says in verse 21 they knew God, but then it says in verse 24 that God gave them over to uncleanness. They chose not to honor him and then he gave them over to uncleanness. I underlined it for you.
