‘knowing that the Father had given all things into his hands, and that he had come from God and was going back to God, … Jesus poured water into a basin a began to wash the disciples feet’ (John 13:3-5, ESV)
Sometimes knowing something and therefore doing something just makes sense. ‘Knowing that he alone truly deserved the award, he stepped forward to accept it’, ‘knowing that he had worked hard for this holiday, he joyfully stepped onto the plane’.
How does ‘knowing that the Father had given all things into his hands, and that he had come from God and was going back to God’
possibly fit with
‘Jesus poured water into a basin a began to wash the disciples feet’?
It makes about as much sense as ‘knowing he was now the world’s richest man, he took up a job cleaning toilets’.
It could only make sense for our God, because it’s his very nature:
‘being in very nature God, he did not consider equality with God something to be exploited, but made himself nothing, taking the every nature of a slave’ (Phil 2:6-7)
