In the Pillar NT Commentary on John
Jesus lays down his life in order to take it up again. Jesus’ sacrificial death was not an end in itself, and his resurrection an afterthought. His death was with the resurrection in view. He died in order to rise, and by his rising to proceed toward his ultimate glorification (12:23; 17:5) and the pouring out of the Spirit (7:37–39) so that others, too, might live.
