All this, and much more, lay involved in Cain's "unbloody sacrifice." He displayed entire ignorance in reference to divine requirements, in reference to his own character and condition as a lost and guilty sinner, and in reference to the true state of that ground, the fruit of which he presumed to offer. No doubt, reason might say, "what more acceptable offering could a man present, than that which he had produced by the labor of his hands, and the sweat of his brow?" Reason, and even man's religious mind, may think thus; but God thinks quite differently; and faith is always sure to agree with God's thoughts. God teaches, and faith believes, that there must be a sacrificed life, else there can be no approach to God.
Thus, when we look at the ministry of the Lord Jesus, we see, at once, that, had he not died upon the cross, all his services would have proved utterly unavailing as regards the establishment of our relationship with God. True, "he went about doing good" all his life; but it was his death that rent the veil. (Matt. xxvii. 51.) Naught but his death could have done so. Had he continued, to the present moment, "going about doing good," the veil would have remained entire, to bar the worshipper's approach into "the holiest of all." Hence we can see the false ground on which Cain stood as an offerer and a worshipper. An unpardoned sinner coming into the presence of Jehovah, to present "an unbloody sacrifice," could only be regarded as guilty of the highest degree of presumption. True, he had toiled to produce this offering; but what of that? Could a sinner's toil remove the curse and stain of sin? Could it satisfy the claims of an infinitely holy God? Could it furnish a proper ground of acceptance for a sinner? Could it set aside the penalty which was due to sin? Could it rob death of its sting, or the grave of its victory? Could it do any or all of these things? Impossible. "Without shedding of blood is no remission." Cain's "unbloody sacrifice," like every other unbloody sacrifice, was not only worthless, but actually abominable, in the divine estimation. It not only demonstrated his entire ignorance of his own condition, but also of the divine character. "God is not worshipped with men's hands as though he needed any thing." And yet Cain thought he could be thus approached. And every mere religionist thinks the same. Cain has had many millions of followers, from age to age. Cain-worship has abounded all over the world. It is the worship of every unconverted soul, and is maintained by every false system of religion under the sun.
Man would fain make God a receiver instead of a giver; but this cannot be; for, "it is more blessed to give than to receive;" and, assuredly, God must have the more blessed place. "Without all contradiction, the less is blessed of the better." "Who hath _first_ given to him?" God can accept the smallest gift from a heart which has learnt the deep truth contained in those words, "of thine own have we given thee;" but, the moment a man presumes to take the place of the "first" giver, God's reply is, "if I were hungry, I would not tell thee;" for "he is not worshipped with men's hands, as though he _needed any thing_, seeing he _giveth_ to _all_ life and breath and _all_ things." The great Giver of "all things" cannot possibly "need any thing." Praise is all that we can offer to God; but this can only be offered in the full and clear intelligence that our sins are all put away; and this again can only be known by faith in the virtue of an accomplished atonement.
My readers may pause, here, and read prayerfully the following scriptures, namely, Psalm i.; Isaiah i. 11-18; and Acts xvii. 22-34, in all of which he will find distinctly laid down the truth as to man's true position before God, as also the proper ground of worship.
Let us now consider Abel's sacrifice. "And Abel, he also brought of the firstlings of his flock, and of the fat thereof." In other words, he entered, by faith, into the glorious truth, that God could be approached by sacrifice; that there was such a thing as a sinner's placing the death of another between himself and the consequence of his sin, that the claims of God's nature and the attributes of his character could be met by the blood of a spotless victim,--a victim offered to meet God's demands, and the sinner's deep necessities. This is, in short, the doctrine of the cross, in which alone the conscience of a sinner can find repose, because, therein, God is fully glorified.
