Romans 1:19-21

ISV(i) 19 For what can be known about God is plain to them, because God himself has made it plain to them. 20 For since the creation of the world God’s invisible attributes—his eternal power and divine nature—have been understood and observed by what he made, so that people are without excuse. 21 For although they knew God, they neither glorified him as God nor gave thanks to him. Instead, their thoughts turned to worthless things, and their senseless hearts were darkened.
