Commentary by ~ John Piper

Today is Maundy Thursday. The name comes from the Latin mandatum, the first word in the Latin rendering of John 13:34, “A new commandment (Mandatum novum) I give to you, that you love one another: just as I have loved you, you also are to love one another.” This commandment was given by the Lord on the Thursday before his crucifixion. So Maundy Thursday is the “Thursday of the Commandment.”
This is the commandment: “Love one another as I have loved you.” But what about Galatians 5:14? “For the whole law is fulfilled in one word: ‘You shall love your neighbor as yourself.’” If the whole law is fulfilled in “Love your neighbor as yourself,” what more can “Love one another as Christ loved you” add to the fulfillment of the whole law?
I would say that Jesus did not replace or change the commandment, “Love your neighbor as you love yourself.” He filled it out and gave it clear illustration. He is saying,
Here is what I mean by “as yourself.” Watch me. I mean: Just as you would want someone to set you free from certain death, so you should set them free from certain death. That is how I am now loving you. My suffering and death is what I mean by ‘as yourself.’ You want life. Live to give others life. At any cost.
So John says, “By this we know love, that he laid down his life for us, and we ought to lay down our lives for the brothers” (1 John 3:16). Was Jesus loving us “as he loved himself”? Listen to Ephesians 5:29-30, “No one ever hated his own flesh, but nourishes and cherishes it, just as Christ does the church, because we are members of his body.”
In the horrors of his suffering Christ was sustained “by the joy that was set before him” (Hebrews 12:2). And that joy was the everlasting gladness of his redeemed people, satisfied in the presence of the risen king.
Therefore, let us see the greatest love in action during these next 24 hours. “Having loved his own who were in the world, he loved them to the end” (John 13:1). And let us be so moved by this love that it becomes our own. “He laid down his life for us, and we ought to lay down our lives for the brothers” This is the commandment. This is the Thursday.
