Psalm 62:12
10 Do not trust in what you can gain by oppression. Do not put false confidence in what you can gain by robbery. If wealth increases, do not become attached to it. 11 God has declared one principle; two principles I have heard: God is strong, 12 and you, O Lord, demonstrate loyal love. For you repay men for what they do.
2 Corinthians 5:10
8 Thus we are full of courage and would prefer to be away from the body and at home with the Lord. 9 So then whether we are alive or away, we make it our ambition to please him. 10 For we must all appear before the judgment seat of Christ, so that each one may be paid back according to what he has done while in the body, whether good or evil. 11 Therefore, because we know the fear of the Lord, we try to persuade people, but we are well known to God, and I hope we are well known to your consciences too. 12 We are not trying to commend ourselves to you again, but are giving you an opportunity to be proud of us, so that you may be able to answer those who take pride in outward appearance and not in what is in the heart.
Notes and References
"... Paul makes it clear that judgment is according to what someone has done ... Was Paul simply borrowing an expression, or was he allowing the Psalm to frame his thinking. The theme that judgment is according to works was commonly accepted in Jewish circles. Paul could also have referenced a number of other Psalms, but deliberately focused on Psalm 62. When the opposition has intensified, he acknowledges twice over that God is his rock (62:2, 6), and his need for refuge. He speaks of the cowardliness and falsehood of men (62:3-4), and of the vanity and greed of men (62:9, 10). David remains confident of the power and of the steadfast love of God (62:11, 12), and it is in that context that he speaks of God rendering to a man according to his work. The contrast in Psalm 62 is between those whose rock and refuge is God, and those who do evil. “The psalm, which ends with the phrase quoted here, sees God’s just judgment according to works as an expression of God’s power and mercy. This deep-rooted Jewish tradition is not denied by Paul, but rather celebrated. If one of the purposes of the letter is to show that God’s justice upstages that of Caesar and Rome, we could expect nothing less ..."
