The Enarrations, or Expositions, on the Psalms

1....“The ungodly has said in himself that he will sin: there is no fear of God before his eyes”. Not of one man, but of a race of ungodly men he speaks, who fight against their own selves, by not understanding, that so they may live well; not because they cannot, but because they will not. For it is one thing, when one endeavours to understand some thing, and through infirmity of flesh cannot; as says the Scripture in a certain place, “For the corruptible body presses down the soul, and the earthly tabernacle weighs down the mind that muses upon many things;” but another when the human heart acts mischievously against itself, so that what it could understand, if it had but good will thereto, it understands not, not because it is difficult, but because the will is contrary. But so it is when men love their own sins, and hate God's Commandments. For the Word of God is your adversary, if you be a friend to your ungodliness; but if you are an adversary to your ungodliness, the Word of God is your friend, as well as the adversary of your ungodliness....
