Galatians has been called the "Declaration of Independence of Christian liberty." Christ our freedom.
1) Freedom must originate from God & not man. You must give yourself to Jesus. You cannot give to others until we give ourselves in love. Not just to deliver man from sin but also to give glory to God.
2) There is One Gospel. Good news to no good news, and illegitimate(alternative), confusion & cursed/their ego, knowledge and understanding.
3) Please God not man or his audience/ Popular rather than faithful!
