Psalms 103:13

13.As a father is compassionate towards his children, The Psalmist not only explains by a comparison what he has already stated, but he at the same time assigns the cause why God so graciously forgives us, which is, because he is a father It is then in consequence of God’s having freely and sovereignly adopted us as his children that he continually pardons our sins, and accordingly we are to draw from that fountain the hope of forgiveness. And as no man has been adopted on the ground of his own merit, it follows that sins are freely pardoned. God is compared to earthly fathers, not because he is in every respect like them, but because there is no earthly image by which his unparalleled love towards us can be better expressed. That God’s fatherly goodness may not be perverted as an encouragement to sin, David again repeats that God is thus favorable only to those who are his sincere worshippers. It is indeed a proof of no ordinary forbearance for God to “make his sun to rise on the evil and on the good,” (Matthew 5:45;) but the subject here treated is the free imputation of the righteousness by which we are accounted the children of God. Now this righteousness is offered only to those who entirely devote themselves to so bountiful a Father, and reverently submit to his word. But as our attainments in godliness in this world, whatever they may be, come far short of perfection, there remains only one pillar on which our salvation can securely rest, and that is the goodness of God.
