I believe this is key: Knowing who He was, and whose He was, was enough - it was everything He needed (nothing else could add anything of substance or significance for him - including human accolades since "He knew what man was made of...").
With that, in this specific instance, He once again displays the act of a humble servant, removing His outer garment and wrapping Himself in a towel, He begins to wash his disciples smelly, dirt-caked feet...and then tells them to live out their lives in this same way. (John 13:1-17)
I'm reminded of Philippians 2:1-11 (the mind-set of Jesus) and, also, Mark 9 where God describes greatness in His eyes: it doesn't consist of seeing wonders or performing miracles or even fasting & praying (all important); instead, greatness is about two things - humility & service (which both stem from love). These are the heart of the kingdom of heaven.
Keeping my eyes fixed on Jesus who came to humbly serve, dying to self & asking God to mold, shape & transform my life to look more & more as He intended.
love journeying together :)
