Our God by Charles Spurgeon
Romans 9 verses 13 to 16

Just as it is written, Jacob I loved, but Esau I hated. What then shall we say? Is God unjust? Not at all, for he says to Moses, I will have mercy on whom I have mercy, and I will have compassion on whom I have compassion. It does not therefore depend on man's desire or effort, but on God's mercy.

God may, if He wills, save the entire human race, or if it pleases Him, He may save none. If He so wills, He may make one man a monument of mercy, and leave his neighbor to reap his due punishment. This is what God has a right to do, and He claims His sovereign prerogative.

No doctrine in the whole Word of God has more excited the hatred of mankind than the truth of the absolute sovereignty of God. Men have no objection to a God who is really no God. I mean by this, a God who shall be the subject of their caprice, a God who shall be a lackey to their will, a God who shall be under their control, they have no objection to such a being as that.

But a God who speaks, and it is done, a God who commands, and it stands fast, a God who does as he wills among the armies of heaven and among the inhabitants of this lower world, such a God as this they cannot endure.

Psalm 115 verse 3
But our God is in the heavens, he does whatever he pleases.

Psalm 135 verses 5-6
For I know that the LORD is great, our Lord is above all gods. Whatever the LORD pleases, He does, in heaven and on earth, in the seas, and all their depths.
