(3.) That it was the effect of the pardon of sin: "For thou hast cast all my sins behind thy back, and thereby hast delivered my soul from the pit of corruption, in love to it." Note, [1.] When God pardons sin he casts it behind his back, as not designing to look upon it with an eye of justice and jealousy. He remembers it no more, to visit for it. The pardon does not make the sin not to have been, or not to have been sin, but not to be punished as it deserves. When we cast our sins behind our back, and take no care to repent of them, God sets them before his face, and is ready to reckon for them; but when we set them before our face in true repentance, as David did when his sin was ever before him, God casts them behind his back. [2.] When God pardons sins he pardons all, casts them all behind his back, though they have been as scarlet and crimson. [3.] The pardoning of the sin is the delivering of the soul from the pit of corruption. [4.] It is pleasant indeed to think of our recoveries from sickness when we see them flowing from the remission of sin; then the cause is removed, and then it is in love to the soul.
