Paul is repeating what he has already said. It may seem to us that all the repetition is a little overkill, but it has a purpose. We must remember that when Scripture repeats itself it is because we need to listen and then to listen again and again. It is an either-or decision the Galatians are making. Either they are saved by faith alone or they will choose to go the route of self-salvation by works. It cannot be both. We cannot add to the gospel without subtracting from it. Jesus and his work on the cross are either all of our value or he is without value. Verse 4 seems to hint at an actuality of losing salvation if the Galatians continue down that course. We will see tomorrow that Paul shows us where our assurance lies as Christians. The bottom line for today is that all Christians need to hear the warning in these verses. Paul is saying that no matter if you insist that you have been converted or you feel like Christ has changed your life. If you are living in such a way that your salvation rests in any way on your performance, you are actually denying salvation by faith alone in Christ and you cannot be saved by him. This is the test and what a beautiful one it is. Paul is preaching that our hope does not rest on our own perfection but on the perfection of Jesus.
