2:25-29 No forms, ordinances, or notions can profit, without regenerating grace, which will always lead to seeking an interest in the righteousness of God by faith. For he is no more a Christian now, than he was really a Jew of old, who is only one outwardly: neither is that baptism, which is outward in the flesh: but he is the real Christian, who is inwardly a true believer, with an obedient faith. And the true baptism is that of the heart, by the washing of regeneration and the renewal of the Holy Ghost; bringing a spiritual frame of mind, and a willing following of truth in its holy ways. Let us pray that we may be made real Christians, not outwardly, but inwardly; in the heart and spirit, not in the letter; baptized, not with water only, but with the Holy Ghost; and let our praise be, not of men, but of God.
26. Therefore if the uncircumcision keep the … law, &c.—Two mistaken interpretations, we think, are given of these words: First, that the case here supposed is an impossible one, and put merely for illustration [Haldane, Chalmers, Hodge]; second that it is the case of the heathen who may and do please God when they act, as has been and is done, up to the light of nature [Grotius, Olshausen, &c.]. The first interpretation is, in our judgment, unnatural; the second, opposed to the apostle's own teaching. But the case here put is, we think, such as that of Cornelius (Ac 10:1-48), who, though outside the external pale of God's covenant, yet having come to the knowledge of the truths contained in it, do manifest the grace of the covenant without the seal of it, and exemplify the character and walk of Abraham's children, though not called by the name of Abraham. Thus, this is but another way of announcing that God was about to show the insufficiency of the mere badge of the Abrahamic covenant, by calling from among the Gentiles a seed of Abraham that had never received the seal of circumcision (see on Ga 5:6); and this interpretation is confirmed by all that follows.
