The vines may be 500 years old. The gnarled vines are as thick as small tree trunks, much thicker than I expected. They sustain life for thousands of grapes. The gardeners graft the grapes into these older and wiser vines. They prune the grapes so that the grapes do not sneak any vines to the earth and try to suckle life on their own. You see, on their own, the grapes cannot provide themselves with the nourishment they need. They need the nourishment to come from the old vines, the thick, hearty vines of 500 years so that the grapes may be succulent and juicy and sweet.
This is what makes a good grape.
Now if some of the branches were broken off, and you, a wild olive shoot, were grafted in among them and participated in the richness of the olive root, do not boast over the branches. But if you boast, remember that you do not support the root, but the root supports you.
Romans 11:17-18
“I am the true vine and my Father is the gardener. He takes away every branch that does not bear fruit in me. He prunes every branch that bears fruit so that it will bear more fruit. Remain in me, and I will remain in you. Just as the branch cannot bear fruit by itself, unless it remains in the vine, so neither can you unless you remain in me. I am the vine; you are the branches. The one who remains in me – and I in him – bears much fruit, because apart from me you can accomplish nothing. John 15:1-5
