Charles H. Spurgeon on Psalms 13:5

"I have trusted in thy mercy; my heart shall rejoice in thy salvation." Though passion possess our bodies, let "patience possess our souls." The law of our profession binds us to a warfare; patiendo vincimus, our troubles shall end, our victory is eternal. Here David's triumph (Psalm 18:38-40), "I have wounded them, that they were not able to rise; they are fallen under my feet. Thou hast subdued under me those that rose up against me. Thou hast also given me the neck of mine enemies," etc. They have wounds for their wounds; and the treaders down of the poor are trodden down by the poor. The Lord will subdue those to us that would have subdued us to themselves; and though for a short time they rode over our heads, yet now at last we shall everlastingly tread upon their necks. Lo, then, the reward of humble patience and confident hope. Speramus et superamus. Deuteronomy 32:31. "Our God is not as their God, even our enemies being judges." Psalm 20:7. "Some put their trust in chariots, and some in horses." But no chariot hath strength to oppose, nor horse swiftness to escape, when God pursues.
