4. And the Lord had respect unto Abel, etc. God is said to have respect unto the man to whom he vouchsafes his favor. We must, however, notice the order here observed by Moses; for he does not simply state that the worship which Abel had paid was pleasing to God, but he begins with the person of the offerer; by which he signifies, that God will regard no works with favor except those the doer of which is already previously accepted and approved by him. And no wonder; for man sees things which are apparent, but God looks into the heart, (1 Samuel 16:7;) therefore, he estimates works no otherwise than as they proceed from the fountain of the heart. Whence also it happens, that he not only rejects but abhors the sacrifices of the wicked, however splendid they may appear in the eyes of men. For if he, who is polluted in his soul, by his mere touch contaminates, with his own impurities, things otherwise pure and clean, how can that but be impure which proceeds from himself? When God repudiates the feigned righteousness in which the Jews were glorying, he objects, through his Prophet, that their hands were “full of blood,” (Isaiah 1:15.) For the same reason Haggai contends against the hypocrites. The external appearance, therefore, of works, which may delude our too carnal eyes, vanishes in the presence of God. Nor were even the heathens ignorant of this; whose poets, when they speak with a sober and well-regulated mind of the worship of God, require both a clean heart and pure hands. Hence, even among all nations, is to be traced the solemn rite of washing before sacrifices. Now seeing that in another place, the Spirit testifies, by the mouth of Peter, that ‘hearts are purified by faith,’ (Acts 15:9;) and seeing that the purity of the holy patriarchs was of the very same kind, the apostle does not in vain infer, that the offering of Abel was, by faith, more excellent than that of Cain. Therefore, in the first place, we must hold, that all works done before faith, whatever splendor of righteousness may appear in them, were nothing but mere sins, being defiled from their roots, and were offensive to the Lord, whom nothing can please without inward purity of heart. I wish they who imagine that men, by their own motion of freewill, are rendered meet to receive the grace of God, would reflect on this. Certainly, no controversy would then remain on the question, whether God justifies men gratuitously, and that by faith? For this must be received as a settled point, that, in the judgment of God, no respect is had to works until man is received into favor. Another point appears equally certain; since the whole human race is hateful to God, there is no other way of reconciliation to divine favor than through faith. Moreover, since faith is a gratuitous gift of God, and a special illumination of the Spirit, then it is easy to infer, that we are prevented (232) by his mere grace, just as if he had raised us from the dead. In which sense also Peter says, that it is God who purifies the hearts by faith. For there would be no agreement of the fact with the statement, unless God had so formed faith in the hearts of men that it might be truly deemed his gift. It may now be seen in what way purity is the effect of faith. It is a vapid and trifling philosophy, to adduce this as the cause of purity, that men are not induced to seek God as their rewarder except by faith. They who speak thus entirely bury the grace of God, which his Spirit chiefly commends. Others also speak coldly, who teach that we are purified by faiths only on account of the gift of regenerations in order that we may be accepted of God. For not only do they omit half the truth, but build without a foundation; since, on account of the curse on the human race, it became necessary that gratuitous reconciliation should precede. Again, since God never so regenerates his people in this world, that they can worship him perfectly; no work of man can possibly be acceptable without expiation. And to this point the ceremony of legal washing belongs, in order that men may learn, that as often as they wish to draw near unto God, purity must be sought elsewhere. Wherefore God will then at length have respect to our obedience, when he looks upon us in Christ.
(232) The word prevented is here used in the sense now rendered somewhat obsolete, though retained in the Liturgy and Articles of the Church of England. We have, in fact, no other word which so well describes the effect of that prevenient grace, which anticipates and goes before every thing that is good in man. — Ed.
