For since the creation of the world God’s
invisible qualities—his eternal power and
divine nature—have been clearly seen, being
understood from what has been made, so that
men are without excuse. Romans 1:20
For it is not those who hear the law who are righteous in God’s sight, but it is those who obey the law who will be declared righteous.
Romans 2:13
(Indeed, when Gentiles, who do not have the law, do by nature things required by the law, they are a law for themselves, even though they do not have the law, since they show that the requirements of the law are written on their hearts, their consciences also bearing witness, and their thoughts now accusing, now even defending them.)
Romans 2:14,15
This will take place on the day when God will judge men’s secrets through Jesus Christ, as my gospel declares. Romans 2:16
Let God be true, and every man a liar.
Romans 3:4b
… so that every mouth may be silenced and the whole world held accountable to God.
Romans 3:19
