Jesus Predicts Peter’s Denial
31When he was gone, Jesus said,
“Now is the Son of Man glorified and God is glorified in Him. 32If God is glorified in Him, God will glorify the Son in Himself, and will glorify Him at once.
33 “My children, I will be with you only a little longer. You will look for Me, and just as I told the Jews, so I tell you now: Where I am going, you cannot come.
34“A new command I give you: Love one another. As I have loved you, so you must love one another.
35By this all men will know that you are my disciples, if you love one another.”
36Simon Peter asked him, “Lord, where are you going?”
Jesus replied, “Where I am going, you cannot follow now, but you will follow later.”
37Peter asked, “Lord, why can’t I follow you now? I will lay down my life for you.”
38Then Jesus answered,
“Will you really lay down your life for Me? I tell you the truth, before the rooster crows, you will disown Me three times!”
“A new command I give you: Love one another. As I have loved you, so you must love one another.”
Ἐντολὴν καινὴν δίδωμι ὑμῖν, ἵνα ἀγαπᾶτε ἀλλήλους
Ἐντολή entolḗ (a feminine noun derived from en, “in,” which intensifies télos, “reach the end, consummation”) focusing on the end-result (objective) of a command and highlighting the nature of a specific order (charge), i.e. “in-context objective”.
Καινός kainós – properly, new in quality (innovation), fresh in development or opportunity – because "not found exactly like this before."
ἀγαπάω agapáō – properly, to prefer, to love; for the believer, preferring to “live through Christ” (1 John 4:9,10), i.e. embracing God's will (choosing His choices) and obeying them. This preeminently refers to what God prefers as He “is love” (1 John 4:8,16).
A New Commandment - This command He gave them as He was about to leave them, to be a badge of discipleship, by which they might be known as His friends and followers, and by which they might be distinguished from all others.
It is called new, not because there was no command before which required people to love their fellow man, for one great precept of the law was that they should love their neighbor as themselves in Leviticus 19:18; “Do not seek revenge or bear a grudge against one of your people, but love your neighbor as yourself. I am Jehovah.”, but it was new because it had never before been made that by which any class or body of people had been known and distinguished.
The Jew was known by his external rites, by his uniqueness of dress, etc.; the philosopher by some other mark of distinction; the military man by his insignia and uniform, etc. In none of these cases had love for each other been the distinguishing and special badge by which they were known.
But in the case of Christians we are not to adopt any special style of dress, badge, or mark but we are to be distinguished by tender and constant attachment to each other in His love. This is the true mark of followers of Christ, you and me.
