Romans 1:5, 12, 20-21

through whom we have received grace and apostleship to bring about the obedience of faith for the sake of his name among all the nations

For his invisible attributes, namely, his eternal power and divine nature, have been clearly perceived, ever since the creation of the world, in the things that have been made. So they are without excuse. For although they knew God, they did not honor him as God or give thanks to him, but they became futile in their thinking, and their foolish hearts were darkened.
