A Christian man does not live in himself, but in Christ and in his neighbor, or else is no Christian: (he is) in Christ by faith (and is) in his neighbor by love. By faith he is carried upwards above himself to God, and by love he sinks back below himself to his neighbor, still always-abiding in God and His love. (Taken from Luther’s treatise, Concerning Christian Liberty).
In Christ by faith and in our neighbors by love. We live by holding a faith that carries us upward to enjoy our Lord and having love we are carried downward to love our neighbors. Loving God and loving neighbor.
