“I am the Lord , and I do not change. That is why you descendants of Jacob are not already destroyed.
Malachi 3:6 NLT
But once he has made his decision, who can change his mind? Whatever he wants to do, he does. So he will do to me whatever he has planned. He controls my destiny. No wonder I am so terrified in his presence. When I think of it, terror grips me.
Job 23:13-15 NLT
If you sin, how does that affect God? Even if you sin again and again, what effect will it have on him? If you are good, is this some great gift to him? What could you possibly give him? No, your sins affect only people like yourself, and your good deeds also affect only humans.
Job 35:6-8 NLT
Warran Wiersbe commentary.
“There is no profit in obeying God” (Job 34:7–9; 35:1–16). Again, Elihu tries to throw Job’s own words back in his face: “I am innocent” (10:7; 12:4; 27:6) and, “What have I gained by obeying God?” (9:29–31; 21:15) Job did make the first statement, but the second is not an accurate quotation of his words. Job never did bargain with God as Satan said he would (1:9, 21; 2:9–10). Eliphaz had discussed this topic (Job 22) and had come to the conclusion that neither man’s piety nor his iniquity could make any difference to the character of God. But Elihu felt it was important to deal with the theme again.
Elihu asked his listeners to look up to the heavens and see how far away the clouds were, and then imagine how far God’s throne was from the earth (35:5–7). Can a man’s sins or good deeds on earth exert such power that they will travel all that distance and change the Almighty in heaven?
Then Elihu asked them to consider human society (vv. 8–16). Our sins or good works may affect people around us (v. 8), but God is not affected by them. Certainly God grieves over man’s sins (Gen. 6:6) and delights in the obedience of the faithful (Ps. 37:23); but our good deeds can’t bribe Him, and our misdeeds can’t threaten Him. God’s character is the same whether men obey Him or disobey Him. God can’t change for the better because He is perfect, and He can’t change for the worse because He is holy.
