F O U N D A T I O N S 20 How will the world know that the gospel is true? Jesus taught us that it would be through the love and unity visible among his disciples. On the night before his death, he prayed for them and for all believers who would come after them: “That they may all be one, just as you, Father, are in me, and I in you, that they also may be in us, so that the world may believe that you have sent me. The glory that you have given me I have given to them, that they may be one even as we are one, I in them and you in me, that they may become perfectly one, so that the world may know that you sent me and loved them even as you loved me.” Oneness in Jesus is a great grace. This grace is not cheap. It demands deeds of love and repentance. It requires giving and receiving forgiveness again and again. Yet if we live in the unity that Jesus prayed for, it will shine out into the whole world as a powerful proclamation of his coming kingdom.* * Peter Riedemann, “What the Church Is,” in Account of Our Religion, Doctrine, and Faith (Rechenschafft unserer Religion, Leer und Glaubens, ca. 1540–1542; published in English 1950).
