Joh 13:2  "During supper, when the devil had already put it into the heart of Judas Iscariot, Simon's son, to betray him,"

There are two distinct spiritual attributes apparent in human hearts and actions.

There is hatred, betrayal, destruction and enmity against God and others.

There is service, care, giving and the Absolute Love of God pouring over and through our lives.

Joh 13:3,4  "Jesus, knowing that the Father had given all things into his hands, and that he had come from God and was going back to God,  rose from supper. He laid aside his outer garments, and taking a towel, tied it around his waist."

You are not always going to understand how God is working in you and through you, Yet if you walk in purity and the love of God, all you do will be holy-sanctified in Him.

Joh 13:5-10  "Then he poured water into a basin and began to wash the disciples' feet and to wipe them with the towel that was wrapped around him.  He came to Simon Peter, who said to him, "Lord, do you wash my feet?"  Jesus answered him, "What I am doing you do not understand now, but afterward you will understand." Peter said to him, "You shall never wash my feet." Jesus answered him, "If I do not wash you, you have no share with me."  Simon Peter said to him, "Lord, not my feet only but also my hands and my head!"  Jesus said to him, "The one who has bathed does not need to wash, except for his feet, but is completely clean. And you are clean, but not every one of you."

It's not going to matter if you or make a difference if you are not walking in purity and love. He is never fooled by our actions, He knows the thoughts and intentions of our heart.

Joh 13:11 "For he knew who was to betray him; that was why he said, "Not all of you are clean."

It is the happiest place you will ever know to walk in love and service to one another by faith and love that flows from constantly keeping your eyes on Him. He is Absolute Love.

Joh 13:12-17  "When he had washed their feet and put on his outer garments and resumed his place, he said to them, "Do you understand what I have done to you?  You call me Teacher and Lord, and you are right, 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 also should do just as I have done to you. Truly, truly, I say to you, a servant is not greater than his master, nor is a messenger greater than the one who sent him. If you know these things, blessed are you if you do them."

Jesus knows His chosen children. He speaks into their souls, they hear Him with the ears of their heart.

Joh 13:18  "I am not speaking of all of you; I know whom I have chosen. But the Scripture will be fulfilled, 'He who ate my bread has lifted his heel against me.'"

Jesus reassures us in everything by His Word.

Joh 13:19  "I am telling you this now, before it takes place, that when it does take place you may believe that I am he."

All you need  is to believe and receive. This is the condition. Rejection of Absolute Love eliminates and disqualifies. Don't continue down that path.

Joh 13:20  "Truly, truly, I say to you, whoever receives the one I send receives me, and whoever receives me receives the one who sent me."
