John Chrysostom

He had said, "I am a prisoner;" but now again he says, that all is of God, as he says, "according to the gift of His grace;" for according to the power of the gift is the dignity of this privilege. But the gift would not have been enough, had it not also implanted in him power.

For a work indeed it was of power, of mighty power, and such as no human diligence was equal to. For he brought three qualifications to the preaching of the word, a zeal fervent and venturous, a soul ready to undergo any possible hardship, and knowledge and wisdom combined. For his love of enterprise, his blamelessness of life, had availed nothing, had he not also received the power of the Spirit.
