John 13:12-20 - The Meaning Of Footwashing
12 So after He had washed their feet and had taken His garments and had reclined again, He said to them, Do you know what I have done to you? 13 You call Me the Teacher, and Lord, and you say well, for I AM. 14 If then I, the Lord and the Teacher, have washed your feet, you also ought to wash one another's feet. 15 For I have given you an example, that you should do as I have done to you.
16 Truly, truly, I say to you, A servant is not greater than his master, neither is he who is sent greater than he who sent him. 17 If you know these things, blessed are you if you do them. 18 I do not speak of you all; I know whom I have chosen; but that the Scripture might be fulfilled, "He who eats bread with me has lifted up his heel against me."
19 From now I tell you before it comes, so that when it happens you may believe that I AM. 20 Truly, truly, I say to you, He who receives whomever I send receives Me. And he who receives Me receives Him who sent Me.
