We cannot pass from the consideration of David's great penitence for his sin without dwelling a little more on some of its features. It is in the fifty-first Psalm that the working of his soul is best unfolded to us. No doubt it has been strongly urged by certain modern critics that that psalm is not David's at all; that it belongs to some other period, as the last verse but one indicates, when the walls of Jerusalem were in ruins;--most likely the period of the Captivity. But even if we should have to say of the last two verses that they must have been added at another time, we cannot but hold the psalm to be the outpouring of David's soul, and not the expression of the penitence of the nation at large. If ever psalm was the expression of the feelings of an individual it is this one. And if ever psalm was appropriate to King David it is this one. For the one thing which is uppermost in the soul of the writer is his personal relation to God. The one thing that he values, and for which all other things are counted but dung, is friendly intercourse with God. This sin no doubt has had many other atrocious effects, but the terrible thing is that it has broken the link that bound him to God, it has cut off all the blessed things that come by that channel, it has made him an outcast from Him whose lovingkindness is better than life. Without God's favour life is but misery. He can do no good to man; he can do no service to God. It is a rare thing even for good men to have such a profound sense of the blessedness of God's favour. David was one of those who had it in the profoundest degree; and as the fifty-first Psalm is full of it, as it forms the very soul of its pleadings, we cannot doubt that it was a psalm of David. The humiliation of the Psalmist before God is very profound, very thorough. His case is one for simple mercy; he has not the shadow of a plea in self-defence. His sin is in every aspect atrocious. It is the product of one so vile that he may be said to have been shapen in iniquity and conceived in sin. The aspect of it as sin against God is so overwhelming that it absorbs the other aspect--the sin against man. Not but that he has sinned against man too, but it is the sin against God that is so awful, so overwhelming. Yet, if his sin abounds, the Psalmist feels that God's grace abounds much more. He has the highest sense of the excellence and the multitude of God's lovingkindnesses. Man can never make himself so odious as to be beyond the Divine compassion. He can never become so guilty as to be beyond the Divine forgiveness. "Blot out my transgressions," sobs David, knowing that it can be done. "Purge me with hyssop," he cries, "and I _shall_ be clean; wash me, and I shall be whiter than the snow. Create in me a clean heart, and renew a right spirit within me."
