God owns the vineyard--Jesus is the vine--we are the branches. All three are necessary if there is to be fruit. Vineyards don't just grow on their own. Someone has to plant them. Someone has to tend the vines. That person is the vine grower. Jesus says that the Father--meaning God--is the vine grower. The vine is the plant itself. Without any vines, there would obviously be no vineyard--no wine. Jesus says that he is the vine. But then Jesus tells his disciples--and we are his disciples--"You are the branches." The branches grow from the vine and, are where the grapes grow. Jesus says to us, "You are the branches." Without branches, there would be no fruit. But it is also true that, without the vine grower (God), there would be no fruit. And without the vine (Jesus) there would be no fruit. The Father, the Son, and the Son's disciples work hand in hand to make a fruitful vineyard. Jesus positions himself in the middle--between us and God. He says, "Abide in me as I abide in you. Just as the branch cannot bear fruit by itself unless it abides in the vine, neither can you unless you abide in me." In other words, if we as Christians are to live spiritually productive lives, we must maintain a spiritual connection to Jesus. Without that connection, we will never produce any spiritual fruit. Without that connection, our lives will come and go without ever meaning anything significant.
