If you knew you were about die, what would you want to say to those you love the most? What would you want to do? It’s a hypothetical question that doesn’t really need an answer except to say that most of us, if not all, would want to say and do those things that really matter, that are of the utmost importance. And so it seems with Jesus too, on the night before he was crucified.
According to the Gospel of John, Jesus washes the feet of his disciples in chapter thirteen and then begins addressing his disciples before he retreats into prayer. The foot washing is important because Jesus is offering his disciples an example of the life he is calling them to live. It’s a life of radical love embodied in the virtues of humility and servitude. It is the life Jesus has lived, the way and truth of the gospel, and why he insists that his disciples must love each other as he has loved them (13:34-35; 15:12).
This life of love embodied in humility and service is the way, truth, and life of Jesus that reflects the gospel, the very Word of God, revealed in Jesus Christ. Compared to the world, this truth is the alternative the disciples are sanctified in (set apart) and sent into the world as witnesses of. This is the reason, Jesus prays in John 17 that his disciples will be one.
“I pray they will be one, Father, just as you are in me and I am in you. I pray that they also will be in us, so that the world will believe that you sent me.” – Jesus Christ, John 17:21
Sanctification and unity point us toward the mission of God (Carson, The Gospel According to John, 566). To be sanctified and sent out as a unified community of disciples is to continue participating in the very mission that God sent Jesus into the world to fulfill.
This is as true today as it was then. Being sanctified is not just a salvation issue and Christian unity is not uniformity achieved in keeping a list of church practices. This is not to suggest that holiness and theology is inconsequential. Some issues, such as the Triune nature of God or Christian marriage, are worthy of our reflection and discernment. But perhaps what matters most is the way we love each other. Our capacity to love one another is what Jesus desires when he prays that we will be one. For in being so one with each other that we will love each other as Christ has loved us, we reflect that love outward to the world around us. That’s a love that draws the rest of the world into the love of God (Gorman, Abide and Go, 124)
This is the truth we all are called to embody, for it signifies that we are united in Jesus Christ as a people known for the very love of God.
