If people mean that man has in himself the power to work in partnership with God's grace they are most wretchedly deluding themselves.
John CalvinThe Fanaticism which discards the Scripture, under the pretense of resorting to immediate revelations is subversive of every principle of Christianity. For when they boast extravagantly of the Spirit, the tendency is always to bury the Word of God so they may make room for their own falsehoods.
John CalvinAt this day . . . the earth sustains on her bosom many monster minds, minds which are not afraid to employ the seed of Deity deposited in human nature as a means of suppressing the name of God. Can anything be more detestable than this madness in man, who, finding God a hundred times both in his body and his soul, makes his excellence in this respect a pretext for denying that there is a God? He will not say that chance has made him different from the brutes; . . . but, substituting Nature as the architect of the universe, he suppresses the name of God.
