John 13:12-20 - The Meaning Of Footwashing
12 When he had washed their feet and put on his clothes and taken his place, he said to them again, "Do you understand what I have been doing to you? 13 You call me Teacher and Master, and you are right, for that is what I am. 14 If I then, your Master and Teacher, have washed your feet, you ought to wash one another's feet too. 15 For I have set you an example, in order that you may do what I have done to you.
16 I tell you, no slave is superior to his master, and no messenger is greater than the man who sends him. 17 Now that you have this knowledge, you will be blessed if you act upon it. 18 I do not mean all of you; I know whom I have chosen; but let the Scripture be fulfilled: " 'He who is eating my bread Has raised his heel against me.'
19 From now on I will tell you things before they happen, so that when they do happen you may believe that I am what I say. 20 I assure you, whoever welcomes any messenger of mine welcomes me and whoever welcomes me welcomes him who has sent me."
