A sinister passenger lurked in the 1860s steamships powering across the Atlantic. Its name? Phylloxera—a microscopic louse with an appetite for roots.
Panic tore through France. Church bells rang in terror as thousands of vineyards shrivelled and died, alongside many livelihoods. In desperation, a hefty reward was advertised: who could stop phylloxera severing the water and nutrient flow from roots to vines? Finally, someone came up with an effective defence: grafting European shoots into phylloxera-resistant American vines.
The process of grafting involves inserting one piece of living material into another so that they now unite and grow as one. It’s how Jesus describes our relationship with Him in John 15:1: “I am the true vine.” He is our only spiritual life-source. “Remain in me” (v. 4)—in other words, “Keep living here with me.” By faith we are grafted to “the true vine” as His branches. And as we obediently respond to Jesus’ words (vv. 7, 10), His life-nurturing Spirit produces God’s fruit in us ( vv. 4–5). Our lives are no longer just ours, but a wonderful extension of His.
Temptations to grow distant from Jesus are like the invasive louse looking to hinder the vital flow of spiritual nourishment. Just like phylloxera-resistant vines, Jesus is our source of life and our defence against worldly tugs and fears. Eternally one with Him, our spiritual sustenance and health comes from cherishing this vital union and life-giving friendship (v. 15).
