2.What have the Judaizers done to the Christians in Galatia?

The Judaizers have bewitched them so they are not obeying the truth of the Gospel.

The Gospel is not a ticket to Heaven. The Gospel is a lifelong program that we are to obey every day. As we obey the Gospel, Christ is formed in us; eternal life is formed in us; the resurrection from the dead is formed in us; we are transformed into the image of Christ; we become an integral, inseparable part of Christ; Christ becomes our life; the Father and the Son take up their abode in us for eternity.

These transformations are taking place in us each day if we are walking in the truth and obeying the Gospel.
