Walther on Law and Gospel

In this episode, we look at John 15:9–17 where Jesus says, "If you keep my commandments, you will abide in my love, just as I have kept my Father’s commandments and abide in his love." Many Christians have taken this to mean that our salvation is earned through obedience to God. How can C. F. W. Walther help us understand these passages using a Law and Gospel distinction?
