The first part of a good work is the will, the second is vigorous effort in the doing of it. God is the author of both. It is, therefore, robbery from God to arrogate anything to ourselves, either in the will or the act.
John CalvinThe human heart has so many crannies where vanity hides, so many holes where falsehood works, is so decked out with deceiving hypocrisy, that it often dupes itself.
John CalvinBecause the will renewed is the Lord's work, it is wrongly attributed to man that he obeys prevenient grace with his will as attendant.
