Now remember that the very heart and centre of that Jewish system was an altar, and that on that altar was sacrificed the expiatory victim. I am not going to insist upon any theory of an atonement, but I do want to urge this, that Christianity is nothing, if it have not explained and taken up into itself that which was symbolised in that old ritual. The very first words from human lips which proclaimed Christ's advent to man were, 'Behold the Lamb of God, which taketh away the sin of the world,' and amongst the last words which Christ spoke upon earth, in the way of teaching His disciples, were these, 'This is My blood, shed for many for the remission of sins.' The Cross of Christ explains my psalm, the Cross of Christ answers the confidence of the Psalmist, which was fed upon the shadow of the good things to come. He has died, the Just for the unjust, that the sins which were laid upon Him might be taken away, covered, and not reckoned to us. Brethren! unless my sins are taken away by the Lamb of God they remain. Unless they are laid upon Christ, they crush me. Unless they are covered by His expiation, they lie there before the Throne of God, and cry for punishment. Unless His blood has wiped out the record that is against us, the black page stands for ever. And to you and me there will be said one day, in a voice which we dare not dispute, 'Pay Me that thou owest!' The blacker the sin the brighter the Christ. I would that I could lay upon all your hearts this belief, 'the blood of Jesus Christ,' and nothing else, 'cleanses from all sin!' III. I will touch in a word only upon the last thought suggested by the text, and that is the blessedness of this removal of sin. As I said, my text is really an exclamation, a gush of rapture from a heart that is tasting the fresh-drawn blessedness of pardon. And the rest of the psalm is little more than an explanation of the various aspects and phases of that blessedness. Let me just run over them in the briefest possible manner.
