3 Lessons prior to Crucifixion

1. (An expression of humility).

Jesus… got up from supper, and laid aside His garments; and taking a towel, He girded Himself. Then He poured water into the basin, and began to wash the disciples’ feet and to wipe them with the towel with which He was girded.
John 13:4-5 NASB

(The Model of a Disciple)

(How?)

2. (An explanation for clarity).

So He came to Simon Peter. He said to Him, “Lord, do you wash my feet?” Jesus answered and said to him, “What I do you do not realize now, but you will understand hereafter.” Peter said to Him, “Never shall you wash my feet!” Jesus answered him, “If I do not wash you, you have no part with Me.” Simon Peter said to Him, “Lord, then wash not only my feet, but also my hands and my head.” Jesus said to him, “He who has bathed needs only to wash his feet, but is completely clean; and you are clean, but not all of you.” For He knew the one who was betraying Him; for this reason He said, “Not all of you are clean.”
John 13:6-11 NASB

(The Model of Love)

(Who?)

3. (An example to follow).

So when He had washed their feet, and taken His garments and reclined at the table again, He said to them, “Do you know what I have done to you? You call me Teacher and Lord; and you are right, for so I am. If I then, the Lord and the Teacher, washed your feet, you also ought to wash one another’s feet. For I gave you an example that you also should do as I did to you.”
John 13:12-15 NASB

(The Model of Serving)

(When?)

While they were eating, Jesus took some bread, and after a blessing, He broke it and gave it to the disciples, and said, “Take, eat; this is My body.” And when He had taken a cup and given thanks, He gave it to them, saying, “Drink from it, all of you; for this is My blood of the covenant, which is poured out for many for forgiveness of sins.”
Matthew 26:26-28 NASB
