John Wesley on Acts 26:24

Festus said, Paul, thou art beside thyself - To talk of men's rising from the dead! And of a Jew's enlightening not only his own nation, but tho polite and learned Greeks and Romans! Nay, Festus, it is thou that art beside thyself. That strikest quite wide of the mark. And no wonder: he saw that nature did not act in Paul; but the grace that acted in him he did not see. And therefore he took all this ardour which animated the apostle for a mere start of learned phrensy.
