Paul's Concern - Forsaking God for a Different Gospel

Paul left no doubt regarding the seriousness of his letter by immediately following his greeting with a pointed rebuke. There was no "catching up" with the Galatian believers or gradual transition into the reason for penning this correspondence. No, he was writing with great concern and a compelling sense of urgency, having learned that they were already moving away from the gospel he had only recently brought to them. And to move away from his gospel was to forsake the God who had called them and to whom they had responded in faith.
