God "will give to each person according to what he has done." [Psalm 62:12]. To those who by persistence in doing good seek glory, honor and immortality, he will give eternal life. To those who are self-seeking and who reject the truth and follow evil, there will be wrath and anger. ... For God does not show favoritism.
-- Romans 2:6-8, 11 NIV.
Now we know that whatever the law says, it says to those who are under the law, so that every mouth may be silenced and the whole world held accountable to God.
--Romans 3:19 NIV.
