19 God shows his anger because everything that may be known about God has been made clear. Yes, God has clearly shown them everything that may be known about him.

20 There are things about God that people cannot see—his eternal power and all the things that make him God. But since the beginning of the world those things have been easy to understand. They are made clear by what God has made. So people have no excuse for the bad things they do.

21 They knew God. But they did not give glory to God, and they did not thank him. Their thinking became useless. Their foolish minds were filled with darkness.
