Judgment Based on Works (Romans 2:6-8 & Revelation 20:13)

He will render to each one according to his works: to those who by patience in well-doing seek for glory and honor and immortality, he will give eternal life; but for those who are self-seeking and do not obey the truth, but obey unrighteousness, there will be wrath and fury.
Romans 2:6-8 ESV

And the sea gave up the dead who were in it, Death and Hades gave up the dead who were in them, and they were judged, each one of them, according to what they had done.
Revelation 20:13 ESV

You can't earn eternal salvation by doing good works, but you will still be judged by your works in the end.
