“… [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.
“Then Jesus cried out and said, ‘He who believes in Me, believes not in Me but in Him who sent Me. And he who sees Me sees Him who sent Me.’” John 12:44-45.

“Now it was the Feast of Dedication in Jerusalem, and it was winter. And Jesus walked in the temple, in Solomon’s porch. Then the Jews surrounded Him and said to Him, ‘How long do You keep us in doubt? If You are the Christ, tell us plainly.’” John 10:22-24.
“As He spoke these words, many believed in Him. Then Jesus said to those Jews who believed Him, ‘If you abide in My word, you are My disciples indeed. And you shall know the truth, and truth shall make you free.’” John 8:30-32.
“They answered Him, ‘We are Abraham’s descendants, and have never been in bondage to anyone. How can you say, “You will be made free”?’” John 8:33.
“And He said to them, ‘You are from beneath; I am from above. You are of this world; I am not of this world. Therefore I said to you that you will die in your sins; for if you do not believe that I am He, you will die in your sins.’” John 8:23-24.
