Charles H. Spurgeon on Psalms 145:20

The LORD preserveth all them that love him. They keep him in their love, and he keeps them by his love. See how these favoured ones have advanced from fearing the Lord and crying to him, even to loving him, and in that love they are secure from all danger. Mark the number of "alls" in these later verses of the Psalm. In each of these God is all in all. But all the wicked will he destroy. Wickedness is an offence to all holy beings, and therefore those who are determined to continue in it must be weeded out. As good sanitary laws remove all creators of pest and plague, so does the moral government of God mark every evil thing for destruction; it cannot be tolerated in the presence of a perfectly holy God. What ruins wicked men frequently become in this life! What monuments of wrath will they be in the world to come! Like Nineveh and Babylon, and other destroyed places, they shall only exist to declare how thoroughly God fulfils his threatenings.
