Throughout his letter to Galatia, Paul has been hammering hard on the anvil of truth. He has been explaining that the theological paradigm has changed due to what Christ did for us. If we receive Him and trust Him, you are saved by faith, not by any merit we can generate on our own. If you believe in Jesus Christ, you are GUILT FREE. In other words, because we are no longer bound by the Law, we have Liberty. However the one thing Christ asks of us is to serve one another and love people, and although that is either extremely easy or extremely hard for some people, the level of trust you put in Christ on this matter will determine your motivation on following this command through.
