Charles H. Spurgeon on Psalms 136:24

And hath redeemed us from our enemies. Israel's enemies brought the people low; but the Lord intervened, and turned the tables by a great redemption. The expression implies that they had become like slaves, and were not set free without price and power; for they needed to be "redeemed." In our case the redemption which is in Christ Jesus is an eminent reason for giving thanks unto the Lord. Sin is our enemy, and we are redeemed from it by the atoning blood; Satan is our enemy, and we are redeemed from him by the Redeemer's power; the world is our enemy, and we are redeemed from it by the Holy Spirit. We are ransomed, let us enjoy our liberty; Christ has wrought our redemption, let us praise his name. For his mercy endureth for ever. Even to redemption by the death of his Son did divine mercy stretch itself. What more can be desired? What more can be imagined? Many waters could not quench love, neither could the floods drown it.

E'en to death upon the tree

Mercy dureth faithfully.
