Romans 1:20-22

There are things about him 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 by what God has made. So people have no excuse for the bad things they do. They knew God, but they did not give glory to God or thank him. Their thinking became useless. Their foolish minds were filled with darkness. They said they were wise, but they became fools.
