Romans 1:20-22

20Ever since God made the world, he has been showing people clearly about himself. We cannot see God. But the things that he has made show us clearly what he is like. We can understand his great power that continues for ever. We can know that he is the true God. So there is no reason for anyone to say, ‘We could not know about God.’

21Those people really knew about God. But they did not respect him as a great God, and they did not thank him. They did not even think clearly any more. Their minds became confused and they did not understand God's message.

22They said that they were wise, but really they became fools.
