"Wherefore also our Lord, who wrought signs and wonders, preached the God of the Jews; and therefore we are right in believing what He preached. But as for you, even if you were really a prophet, and performed signs and wonders, as you promise to do, if you were to announce other gods besides Him who is the true God, it would be manifest that you were raised up as a trial to the people of God; and therefore you can by no means be believed. For He alone is the true God, who is the God of the Jews; and for this reason our Lord Jesus Christ did not teach them that they must inquire after God, for Him they knew well already, but that they must seek His kingdom and righteousness,
