Verse 34 sets up all of John 13-17 (and really how God feels about us in general/our right response to Him). Just as Jesus loved, so we are to love one another. We aren’t just doing whatever we want however we want. We have been extravagantly loved to extravagantly love others.
Jesus washing feet shows this. He takes on the role of a servant and serves to show His love. Do you do this?
He shows this love by coming to earth in the first place (John 3:16). He loves us, He left eternity to enter time/space/matter/human flesh to show us the extant of His love. What a good God! What does this mean to you?
It has meant the world to me!
