Charles H. Spurgeon on Psalms 62:12

Also unto thee, O Lord, belongeth mercy. 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. It belongeth unto thee, as thy prerogative and peculiar excellency. Mercy is a peculiar jewel of his crown. Or, thine, O Lord, is mercy. Nothing amongst the creature deserves the name of mercy but his own. Nothing is worthy to be so called, but what is proper and peculiar to God. Or, with thee is mercy, as it is expressed elsewhere. Ps 130:4,7. It is with him; that is, it is inseparable from his nature. He is merciful in a way peculiar to himself, "the Father of mercies." 2Co 1:3. William Wisheart.
