An age is a part of the world, which is the satanic system (see note Eph. 2:21b). According to the context of this book, the present evil age here refers to the religious world, the religious course of the world, the Jewish religion. This is confirmed by Gal. 6:14-15, where circumcision is considered a part of the world — the religious world, which to the apostle Paul was crucified. Here the apostle emphasized that the purpose of Christ's giving Himself for our sins was to rescue us, to pluck us, out of the Jewish religion, the present evil age. This is to release God's chosen people from the custody of the law (Gal. 3:23), to bring them out of the sheepfold (John 10:1, 3), according to the will of God. Thus, in his opening word Paul indicated what he was going to deal with: he wanted to rescue the churches, which were distracted by Judaism with its law, and bring them back to the grace of the gospel.
