“God is wise in heart and mighty in strength.”

Then Job answered and said: “Truly I know it is so, But how can a man be righteous before God? If one wished to contend with Him, He could not answer Him one time out of a thousand. God is wise in heart and mighty in strength. Who has hardened himself against Him and prospered? He removes the mountains, and they do not know When He overturns them in His anger; He shakes the earth out of its place, And its pillars tremble; He commands the sun, and it does not rise; He seals off the stars; He alone spreads out the heavens, And treads on the waves of the sea;
Job 9:1-8 - NKJV.  
 

What shall we say then? Is there unrighteousness with God? Certainly not! For He says to Moses, “I will have mercy on whomever I will have mercy, and I will have compassion on whomever I will have compassion.” So then it is not of him who wills, nor of him who runs, but of God who shows mercy. For the Scripture says to the Pharaoh, “For this very purpose I have raised you up, that I may show My power in you, and that My name may be declared in all the earth.” Therefore He has mercy on whom He wills, and whom He wills He hardens. You will say to me then, “Why does He still find fault? For who has resisted His will?” But indeed, O man, who are you to reply against God? Will the thing formed say to him who formed it, “Why have you made me like this?” Does not the potter have power over the clay, from the same lump to make one vessel for honor and another for dishonor?
Romans 9:14-21 - NKJV
