As George Bowen wrote:
It is the vocation of every believer, in every generation, to afford in his own person the evidence that Christ has risen. Art thou a Christian? Then art thou one whom Christ has chosen to convey to men the proof that He is risen. This is thy vocation. Wilt thou roll back the stone upon the sepulchre and make the world believe that Christ is still there? This thou art actually doing if thou walk not in the Spirit.
— The Gospel of the Comforter, Chapter 9.
