God has spoken once, Twice I have heard this: That power belongs to God. Also to You, O Lord, belongs mercy . . . (Psalm 62:11–12, NKJV)
We love Him because He first loved us. (1 John 4:19, NKJV)
We stand amazed at the power of God. We worship him for his great strength. The sound of the roar of crashing ocean waves or standing at the base of a vast mountain range gives us a very real sense of just how small we are and just how big he is. Therefore we direct our worship to him because we recognize a greatness which surpasses all others.
But there is something winsome about his divine love and mercy. The disciple John said that we possess the ability to love, not because God is powerful, but because he poured out his love upon us.
Something more is necessary to invite us to a dependence on God than his bare power and ability to help us. There must be also a firm persuasion of the promptitude and readiness of his will to do what he is able; and this we have in the other attribute of his mercy…. “Unto thee, “unto thee alone, and unto none else. The most tender mercy amongst the creatures is none at all, being compared with the divine mercy. . . Mercy is a peculiar jewel of his crown.
– William Wisheart quoted in Charles Spurgeon, Treasury of David, Vol III, p. 62
