Providentially, he finds himself in Jerusalem, the site of Christ's execution and, thus, the holiest city for Christians. While there, Godric experiences a truly powerful conversion and dedicates his life from then on to Christ. His first act of penance is to give up shoes in imitation of Jesus, who wore no shoes as he carried his cross to Calvary. Though now sincerely devoted, God does not stop giving him supernatural guidance. While staying with Elric, Godric learns, through a vision once again, that he will be a hermit and glimpses the woods which will be his home. He continues to experience visions and miracles as he spends the last several decades of his life by Wear: visits from the Virgin Mary, admonition from John the Baptist, and, once, even a glimpse of Christ's face.
