Christ's joy

As the Father has loved me, so have I loved you. Now remain in my love. If you obey my commands, you will remain in my love, just as I have obeyed my Father's commands and remain in his love. I have told you this so that my joy may be in you and that your joy may be complete.

- John 15:9-11

As I was reading this passage, for some reason it struck me, "What is Christ's joy?" It says that he tells his disciples this so that his joy may be in them and that joy may be complete, so what is his joy? Is it different from the joy that we should have as Christians?

After reading further in the passage, it seemed like the answer was no. Having Christ's joy is part of the complete joy that we should have. His joy was to love us enough that he would suffer and lay his life down for us (John 15:13). By having this joy in us, we can say that the troubles we may go through in this life for Christ's sake are worth it because he loved us enough to die for us, and we love him enough to suffer for him. Joy should come from that. Aside from all the other sources of joy in a Christian's life (see Piper's article on joy), I think that the joy that comes from Jesus is the glue that holds it all together, that without it our joy would not be complete.
