Romans 1
20 Ref For from the first making of the world, those things of God which the eye is unable to see, that is, his eternal power and existence, are fully made clear, he having given the knowledge of them through the things which he has made, so that men have no reason for wrongdoing:
21 Ref Because, having the knowledge of God, they did not give glory to God as God, and did not give praise, but their minds were full of foolish things, and their hearts, being without sense, were made dark.
