“So when He had washed their feet, taken His garments, and sat down again, He said to them, ‘Do you know what I have done to you? You call Me Teacher and Lord, and you say well, for so I am. If I then, your Lord and Teacher, have washed your feet, you also ought to wash one another’s feet. For I have given you an example, that you should do as I have done to you. Most assuredly, I say to you, a servant is not greater than his master; nor is he who is sent greater than he who sent him.’” John 13:12-15.
“… [Jesus] rose from supper and laid aside His garments, took a towel and girded Himself. After that, He poured water into a basin and began to wash the disciples’ feet, and to wipe them with the towel with which He was girded.” John 13:4-5.
It is this majestic person Jesus who “rose from supper and laid aside His garments, took a towel and girded Himself.” Christ, being the eternal God in heaven, laid aside His heavenly robes along with His prerogatives as God and became a Man, and not just a Man but a servant, to minister to mankind.
“Now before the feast of the Passover, when Jesus knew that His hour had come that He should depart from this world to the Father, having loved His own who were in the world, He loved them to the end.” John 13:1.
