“You are My friends if you do what I command you” (v14). Obeying Jesus does not save us; that happens when we trust Him to forgive and cleanse us. However, as we grow in faith, abiding in Jesus daily, the new life in us is evident by our changed behavior - our obedience. Like our Savior, we begin to love others sacrificially (v13,17), and we begin following the ways of God’s Kingdom, which sets us apart from the world (v19-23).
“But when the Helper comes …” (v26). We aren’t alone in trying to live for Jesus; God has sent His Spirit to encourage and strengthen us in our witness.
