He sought this knowledge among the contending schools of philosophy, but always in vain, till at last God himself appeased the thirst which He had created. One day, while Justin was walking by the seashore, meditating on the thought of God, an old man met him and questioned him on the subject of his doubts; and when he had made Justin confess that the philosophers taught nothing certain about God, he told him of the writings of the inspired prophets and of Jesus Christ Whom they announced, and bade him seek light and understanding through prayer. The Scriptures and the constancy of the Christian martyrs led Justin from the darkness of human reason to the light of faith. In his zeal for the Faith he travelled to Greece, Egypt, and Italy, gaining many to Christ. At Rome he sealed his testimony with his blood, surrounded by his disciples in 165. "Do you think," the prefect said to Justin, "that by dying you will enter heaven, and be rewarded by God?" "I do not think," was the Saint's answer; "I know."
