Methodius of Olympus

Therefore it is in our power to will not to think these things; but not to bring it about that they shall pass away, so as not to come into the mind again; for this does not lie in our power, as I said; which is the meaning of that statement, "The good that I would, I do not; "for I do not will to think the things which injure me; for this good is altogether innocent. But "the good that I would, I do not; but the evil which I would not, that I do; "not willing to think, and yet thinking what I do not will. And consider whether it was not for these very things that David entreated God, grieving that he thought of those things which he did not will: "O cleanse Thou me from my secret faults. Keep Thy servant also from presumptuous sins, lest they get the dominion over me; so shall I be undefiled, and innocent from the great offence." And the apostle too, in another place: "Casting down imaginations, and every high thing that exalteth itself against the knowledge of God, and bringing into captivity every thought to the obedience of Christ."
