But because faith makes sons of God, it also makes coheirs with Christ. Therefore, because by our works we do not merit justification, through which we are made sons of God, and coheirs with Christ, we do not by our works merit eternal life; for faith obtains this, because faith justifies us and has a reconciled God. But eternal life is due the justified, according to the passage Rom. 8, 30: Whom He justified, them He also glorified. Paul, Eph. 6, 2, commends to us the commandment concerning honoring parents, by mention of the reward which is added to that commandment where he does not mean that obedience to parents justifies us before God, but that, when it occurs in those who have been justified, it merits other great rewards. Yet God exercises His saints variously, and often defers the rewards of the righteousness of works in order that they may learn not to trust in their own righteousness, and may learn to seek the will of God rather than the rewards, as appears in Job, in Christ, and other saints. And of this, many psalms teach us, which console us against the happiness of the wicked, as Ps. 37, 1: Neither be thou envious. And Christ says, Matt. 5, 10: Blessed are they which are persecuted for righteousness' sake; for theirs is the kingdom of heaven. By these praises of good works, believers are undoubtedly moved to do good works. Meanwhile, the doctrine of repentance is also proclaimed against the godless, whose works are wicked; and the wrath of God is displayed, which He has threatened all who do not repent. We therefore praise and require good works, and show many reasons why they ought to be done. Thus of works Paul also teaches when he says, Rom. 4, 9 sq., that Abraham received circumcision, not in order that by this work he might be justified; for by faith he had already attained it that he was accounted righteous. But circumcision was added in order that he might have in his body a written sign, admonished by which he might exercise faith, and by which also he might confess his faith before others, and by his testimony might invite others to believe. By faith Abel offered unto God a more excellent sacrifice, Heb. 11, 4. Because, therefore, he was just by faith, the sacrifice which he made was pleasing to God, not that by this work he merited the remission of sins and grace, but that he exercised his faith and showed it to others, in order to invite them to believe.
