[15:12] 1 sn Now the reference to the commandments (plural) in 15:10 have been reduced to a singular commandment: The disciples are to love one another, just as Jesus has loved them. This is the ‘new commandment’ of John 13:34, and it is repeated in 15:17. The disciples’ love for one another is compared to Jesus’ love for them. How has Jesus shown his love for the disciples? This was illustrated in 13:1-20 in the washing of the disciples’ feet, introduced by the statement in 13:1 that Jesus loved them “to the end.” In context this constitutes a reference to Jesus’ self-sacrificial death on the cross on their behalf; the love they are to have for one another is so great that it must include a self-sacrificial willingness to die for one another if necessary. This is exactly what Jesus is discussing here, because he introduces the theme of his sacrificial death in the following verse. In John 10:18 and 14:31 Jesus spoke of his death on the cross as a commandment he had received from his Father, which also links the idea of commandment and love as they are linked here. One final note: It is not just the degree or intensity of the disciples’ love for one another that Jesus is referring to when he introduces by comparison his own death on the cross (that they must love one another enough to die for one another) but the very means of expressing that love: It is to express itself in self-sacrifice for one another, sacrifice up to the point of death, which is what Jesus himself did on the cross (cf. 1 John 3:16).
