Charles H. Spurgeon on Psalms 106:11

And the waters covered their enemies: there was not one of them left. The Lord does nothing by halves. What he begins he carries through to the end. This, again, made Israel's sin the greater, because they saw the thoroughness of the divine justice, and the perfection of the divine faithfulness. In the covering of their enemies we have a type of the pardon of our sins; they are sunk as in the sea, never to rise again; and, blessed be the Lord, there is "not one of them left." —Not one sin of thought, or word, or deed, the blood of Jesus has covered all. "I will cast their iniquities into the depths of the sea."
