Francis had soon occasion to put these lessons in practice. As he was riding across the plains of Assisi, he perceived a leper coming straight to him. At first he felt horror-stricken, but calling to mind that he had formed a resolution to labor to attain perfection, and that, in order to be a soldier of Jesus Christ, it was necessary to begin by obtaining a victory over self, he dismounted, kissed the leper, and gave him an alms. When he again mounted his horse, he no longer saw any one, though he looked all round the plain. Filled with astonishment, and transported with joy, he fell on his knees to thank God, and formed a firm resolution to aim at still greater perfection. This is the effect of generous and courageous efforts, they draw down fresh graces, and reanimate our courage. He acquired also more inclination for retirement, he had no longer any liking but for solitude, for those places which were adapted to the holy sorrow of penance, where he unceasingly addressed himself to God in fervent prayer, accompanied by lamentations, which cannot be described: God at length favorably heard him. His fervor daily increasing, insomuch that he was wholly absorbed in God, Jesus Christ appeared to him as if attached to the cross. His soul, at this stupendous scene, was wholly penetrated, and, as it were, dissolved, and the image of his crucified Saviour became from that time so strongly and intimately imprinted on his heart, that every time it recurred to his mind, he had a difficulty in restraining his sobs and tears.
