In Pisidian Antioch, Paul recounted the history of Israel up to the time of Jesus and highlighted His resurrection as a point of transition to a new phase in redemptive history.[i] “Through [Jesus],” he said, “everyone who believes is justified from everything you could not be justified from by the law of Moses” (Acts 13:39). The apostle demonstrated to the Galatians how the Mosaic Law was in effect only until “the Seed” referred to in the Abrahamic covenant arrived (Gal. 3:6-9). The “old” covenant had been a glorious one, but “what was glorious has no glory now in comparison with the surpassing glory” of the new covenant (3:10).
