The idea expressed by all sacrifices of expiation was, that the victim took the place of the sinner, and received the punishment due to him. The sacrifice was an acknowledgment on the sinner's part that by his sin he had incurred penalty; and it was a prayer on the sinner's part that he might be washed from the guilt he had contracted, and might return to life with the blessing and favour of God upon him. Of course, it was seen, and said by the heathen themselves, as well as by the Jews, that the blood of bulls and goats had in itself no relation to moral defilement. It was used in sacrifice merely as a telling way of saying that sin was acknowledged and pardon desired, but always with the idea of substitution more or less explicitly in the mind. And the ideas which were inevitably associated with sacrifice were transferred to Jesus by His immediate disciples. And this transference of the ideas connected with sacrifice to Himself and His death was sanctioned--and indeed suggested--by Jesus, when, at the Last Supper, He said, "This cup is the New Testament in My Blood, which is shed for many, for the remission of sins."
But here the question at once arises: In what sense was the Blood of Christ shed for the remission of sins? In what sense was He a substitute and victim for us? Before we try to find an answer to this question, two preliminary remarks may be made--first, that our salvation depends not on our understanding how the death of Christ takes away sin, but upon our believing that it does so. It is very possible to accept the pardon of our sin, though we do not know how that pardon has been obtained. We do not understand the methods of cure prescribed by the physician, nor could we give a rational account of the efficacy of his medicines, but this does not retard our cure if only we use them. To come into a perfect relation to God we do not require to understand how the death of Christ has made it possible for us to do so; we need only to desire to be God's children, and to believe that it is open to us to come to Him. Not by the intellect, but by the will, are we led to God. Not by what we know, but by what we desire, is our destiny determined. Not by education in theological requirements, but by thirst for the living God, is man saved.
And, second, even though we carry over to the death of Christ the ideas taught by Old Testament sacrifice, we commit no enormous or misleading blunder. Christ Himself suggested that His death might be best understood in the light of these ideas, and even though we are unable to penetrate through the letter to the spirit, through the outward and symbolic form to the real and eternal meaning of the sacrifice of Christ, we are yet on the road to truth, and hold the germ of it which will one day develop into the actual and perfect truth. Impatience is at the root of much unbelief and misconception and discontent; the inability to reconcile ourselves to the fact that in our present stage there is much we must hold provisionally, much we must be content to see through a glass darkly, much we can only know by picture and shadow. It is quite true the reality has come in the death of Christ, and symbol has passed away; but there is such a depth of Divine love, and so various a fulfilment of Divine purpose in the death of Christ, that we cannot be surprised that it baffles comprehension. It is the key to a world's history; for aught we know, to the history of other worlds than ours; and it is not likely that we should be able to gauge its significance and explain its _rationale_ of operation. And therefore, if, without any sluggish indifference to further knowledge, or merely worldly contentment to know of spiritual things only so much as is absolutely necessary, we yet are able to use what we do know and to await with confidence further knowledge, we probably act wisely and well. We do not err if we think of Christ as our Sacrifice; nor even if we somewhat too literally think of Him as the Victim substituted for us, and ascribe to His Blood the expiatory and cleansing virtue which belonged symbolically to the blood of the ancient sacrifices.
