The application of this to the question of a sinner's peace is very plain. The Lord Jesus Christ having shed His precious blood, as a perfect atonement for sin, has taken it into the presence of God, and sprinkled it there; and God's testimony assures the believing sinner that everything is settled on his behalf--settled not by his estimate of the blood, but by the blood itself, which God estimates so highly, that because of it, without a single jot or tittle added thereto, He can righteously forgive all sin, and accept the sinner as perfectly righteous in Christ. How can any one ever enjoy settled peace if his peace depends upon his estimate of the blood? Impossible! The loftiest estimate which the human mind can form of the blood must fall infinitely short of its divine preciousness; and therefore, if our peace were to depend upon our valuing it as we ought, we could no more enjoy settled peace than if we were seeking it by "works of law." There must either be a sufficient ground of peace in the blood _alone_, or we can never have peace. To mix up our estimate with it, is to upset the entire fabric of Christianity, just as effectually as if we were to conduct the sinner to the foot of mount Sinai, and put him under a covenant of works. Either Christ's atoning sacrifice is sufficient or it is not. If it is sufficient, why those doubts and fears? The words of our _lips_ profess that the work is finished; but the doubts and fears of the _heart_ declare that it is not. Every one who doubts his full and everlasting forgiveness, denies, so far as he is concerned, the completeness of the sacrifice of Christ. But there are very many who would shrink from the idea of deliberately and avowedly calling in question the efficacy of the blood of Christ, who, nevertheless, have not settled peace. Such persons profess to be quite assured of the sufficiency of the blood, _if_ only _they_ were sure of an interest therein--_if only_ they had the right kind of faith. There are many precious souls in this unhappy condition. They are occupied with their interest and their faith, instead of with Christ's blood and God's word. In other words, they are looking in at self, instead of out at Christ. This is not faith; and, as a consequence, they have not peace. An Israelite within the blood-stained lintel could teach such souls a most seasonable lesson. He was not saved by his interest in, or his thoughts about, the blood, but simply by the blood. No doubt he had a blessed interest in it, and he would have his thoughts likewise; but then God did not say, When I see your interest in the blood, I will pass over you. Oh, no! THE BLOOD, in all its solitary dignity and divine efficacy, was set before Israel; and had they attempted to place even a morsel of unleavened bread beside the blood, as a ground of security, they would have made Jehovah a liar, and denied the sufficiency of His remedy.
