Thus the Christian runs along the appointed course until he passes from death to life and is crowned with the crown of righteousness. In this order nothing can be added or taken away without disrupting everything. But the main thing here is the hope of salvation solely in Christ Jesus the Lord. This is the heart of Christianity. Whoever strikes it cuts off life in Christ. Christ the Lord is present only in the one who is such. In the one whose hope in the Lord alone grows weak, the bond with the Lord weakens. From the one who rests his hope on anything else besides Him, He withdraws as unnecessary, not sought by the needs and groanings of a contrite heart. This was the misfortune that happened to the Galatians. They had not yet been circumcised and bound themselves to the Law. But their will had already inclined toward this; see blessed Augustine. Their hope of salvation only in the Lord had been shaken. For this reason the Lord withdrew from them. "You have become estranged from Christ," he says. You have been emptied by Him. You have become vacant, and He is no longer in you. The judgment of God does not delay. The deed had not yet followed. They had only inwardly resolved in their thoughts to Judaize. Yet God's sentence concerning them had already taken place. The punishment had been carried out in deed: Christ had withdrawn from them. Or here the Apostle expresses only the general proposition. Those who seek justification in the Law are made void of Christ. He threatens that the same will happen to them if they rest their hopes on the Law. "You have fallen from grace." This may be regarded both as a consequence and as a cause of the preceding statement. Christ, Who before filled and sustained you, has withdrawn from you. You have remained without Him. You have fallen away from Him and from all the grace given in Him. Or it may be understood thus. Since you have fallen away in hope from grace and have begun to hope to receive salvation apart from it, Christ has withdrawn from you. For in Him is all grace. Grace is either God's good pleasure, by which all that is necessary for salvation is poured out upon the believer, or this very saving power sent down into the heart. There it forms the saving order and sustains it. In reality the two are inseparable. Both are in the one Lord Jesus Christ. Whoever has become void of Christ loses both. By placing their hope in the Law, the Galatians inwardly fell away from grace, from that law of salvation by which it is given only to those who hope in God's good pleasure in Christ Jesus. Consequently, the good pleasure itself was taken from them. With it went the saving powers, and they were left with nothing. "By this the Apostle shows the extreme danger of their position. If the one who flees to the Law does not find salvation in it, and meanwhile falls away from grace, what remains for him except inevitable punishment? For the Law has no power, and grace does not receive him" (Chrysostom).
