Paul’s main point in the book of Galatians is that because of Jesus, you are free from rules, regulations, rituals, and even religion. None of those things have anything to do with establishing a relationship with God. The most important thing for you to understand is that the only thing you have to do be right with God is to receive the Gospel. Paul explains to us how the Gospel is the one central message that makes Christianity the only true faith worth believing and the only true faith worth living. With this in mind, Paul jumps right into these Galatians because of a problem going on within their church, and he tells them what the one and only Gospel really is.
