These letters of Paul are sent for different reasons. The letter to the Galatian churches, to the congregations in Galatia, is one of rebuke and correction. Apostasy/rebellion was taking place, they were turning away from the true Gospel of the Kingdom, the Gospel of Jesus Christ.
It is this Jesus that hung on a cross for you, who died for you, who rose on the third day for you, that is calling you to walk with Him in repentance and obedience. I don’t know what your next step is, but I do know this: You have one. God will never be finished taking you deeper in faith. There is always a next step. If you have not agreed to walk with God, then where are you headed?
