But lest any one should meet us with the question, What should prevent that He whom we call Christ, being a man born of men, performed what we call His mighty works by magical art, and by this appeared to be the Son of God? we will now offer proof, not trusting mere assertions, but being of necessity persuaded by those who prophesied [of Him] before these things came to pass, for with our own eyes we behold things that have happened and are happening just as they were predicted; and this will, we think appear even to you the strongest and truest evidence.
