Do you see how he proved that those who cling to the law came under the curse because it is impossible to fulfill it? But how does faith have this power to justify? He had announced this earlier, and proved it with great force.
Since the law was powerless to bring man to justification, another sufficient means was found: faith, which by itself makes possible what was impossible under the law.
