The main emphasis of John 15 is abiding in Christ. Just like a branch broken from a tree, once it is removed from its source of life it is no longer able to continue to grow. We need to be sure that we stay connected to Jesus.
How do you know how to get where you are going? Today we use technology like GPS. The disciples needed different kind of directions. They needed spiritual directions. Jesus tells them to believe in the “great hope” of his return. He said that He is “the way, the truth and the life.”
Jesus took on the role of the lowliest person present to wash the feet of his disciples. Jesus models absolute humble service, teaching us how we ought to serve others. The way others know that we are followers of Christ is how well we love one another. We need the cleansing of Jesus if we are going to live lives of love.
