Then there is another thought here, that the past of God is a plea with God for present forgiveness. 'Thy name' in Scripture means the whole revelation of the divine character, and thus the Psalmist looks back into the past, and sees there how God has, all through the ages, been plenteous in mercy and ready to forgive all that called upon Him; and he pleads that past as a reason for the present and for the future. Thousands of years have passed since David, if he was the Psalmist, offered this prayer; and you and I can look back to the blessed old story of _his_ forgiveness, so swift, so absolute and free, which followed upon confession so lowly, and can remember that infinitely pathetic and wonderful word which puts the whole history of the resurrection and restoration of a soul into two clauses. 'David said unto Nathan, I have sinned against the Lord: and Nathan said unto David'--finishing the sentence--'And the Lord hath made to pass the iniquity of thy sin.' What He was He is; what He is He will be. 'For Thy name's sake, pardon mine iniquity.'
There is yet another thought that may be suggested. The divine forgiveness is in order that men may know Him better. That is represented in Scripture as being the great motive of the divine actions--'for the glory of Thine own name.' That may be so put as to be positively atrocious, or so as to be perfectly divine and lovely. It has often been put, by hard and narrow dogmatists, in such a way as to make God simply an Almighty selfishness, but it ought to be put as the Bible puts it, so as to show Him as an Almighty love. For why does He desire that His name should be known by us but for our sakes, that the light of that great Name may come to us, 'sitting in darkness and in the shadow of death,' and that, knowing Him for what He is, we may have peace, and rest, and joy, and love, and purity? It is pure benevolence that makes Him act, 'for the glory of His great name'; sweeping away the clouds that a darkened earth may expand and rejoice, and all the leaves unfold themselves, and every bird sing, in the restored sunshine.
And there is nothing that reveals the inmost hived sweetness and honey of the name of God like the assurance of His pardon. 'There is forgiveness with Thee that Thou mayest be feared.' Oh, dear brethren! unless you know God as the God that has forgiven you, your knowledge of Him is but shallow and incomplete, and you know not the deepest blessings that flow to them who find that this is life eternal to know the only true God as the all-forgiving Father.
Note the connection between the Psalmist's plea and the New Testament plea. David said, 'For Thy name's sake, pardon,' we say, 'For Christ's sake, forgive.' Are the two diverse? Is the fruit diverse from the bud? Is the complete noonday diverse from the blessed morning twilight? Christ _is_ the Name of God, the Revealer of the divine heart and mind. When Christian men pray 'For the sake of Christ,' they are not bringing a motive, which is to move the divine love which else lies passive and inert, because God's love was the cause of Christ's work not Christ's work the cause of God's love, but they are expressing their own dependence on the Great Mediator and His work, and solemnly offering, as the ground of all their hope, that perfect sacrifice which is the medium by which forgiveness reaches men, and without which it is impossible that the government of the righteous God could exist with pardon. Christ has died; Christ, in dying, has borne the sins of the world; that is, yours and mine. And therefore the pardon of God comes to us through that channel, without, in the slightest degree, trenching on the awfulness of the divine holiness or weakening the sanctities of God's righteous retributive law. 'For Christ's sake hath forgiven us' is the daylight which the Psalmist saw as morning dawn when he cried, 'For Thy name's sake, pardon mine iniquity.'
