Have you ever seen the damage to trees after a heavy windstorm? Limbs and branches are often strewn about the landscape, and some land on houses and cars, causing even more damage. Often those branches still have healthy-looking leaves and fruit, but we know they will soon die. When a branch is severed from the main trunk, its vitality is lost. Its lifeline is gone. Its leaves will wither and die, and its fruit will decay.

Jesus conveys a similar message in John 15, saying, “I am the vine; you are the branches.” He helps us to see that if we break away from him—the true vine—we will not have his spiritual life in us. Though we may appear vibrant for a while, we will lack the capacity to produce spiritual life, health, or fruit on our own. Only if we stay connected to Jesus can we bear spiritual fruit that endures.

The main function of a vine such as a grapevine is to bear fruit. And fruit-bearing sums up our purpose as followers of Jesus. In fact, Jesus explains that every branch that bears no fruit will be cut off. But with his Spirit living in us, we will yield fruit such as love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, and self-control (see Galatians 5:22-23). This is our calling.
