Romans 1:20-21, 32

For ever since the world was created, people have seen the earth and sky. Through everything God made, they can clearly see his invisible qualities—his eternal power and divine nature. So they have no excuse for not knowing God. Yes, they knew God, but they wouldn’t worship him as God or even give him thanks. And they began to think up foolish ideas of what God was like. As a result, their minds became dark and confused.

They know God’s justice requires that those who do these things deserve to die, yet they do them anyway. Worse yet, they encourage others to do them, too.
