Ambrose of Milan, on Titus 1:2

“Unto the hope of life everlasting, which God, who lieth not, hath promised before the times of the world:”

“But God can neither be in doubt, nor can he be deceived. For he only is in doubt who is ignorant of the future. One who has predicted one thing while something else has happened is deceived about the future. Not so with God. What is plainer than the fact that Scripture states the Father to have said one thing of the Son and that the same Scripture proves another thing to have taken place? The Son was beaten, he was mocked, was crucified and died. He suffered much worse things in the flesh than those servants who had been appointed before. Was the Father deceived? Was he ignorant of it? Was he unable to give help? The One who is the truth cannot make a mistake. It is written that "the ever-truthful God cannot lie." How could he who knows all be ignorant? What could he not do, who could do all?”
