“There is not any thing done in us or by us that is holy and acceptable unto God, but is an effect of the Holy Spirit. It is His operation in us and by us. Without Him we can do nothing, for without Christ we cannot (John 15:5), and by the Holy Spirit alone is the grace of Christ communicated unto us and wrought in us. By Him we are regenerated; by Him we are sanctified; by Him we are cleansed; by Him we are assisted in and unto every good work.”
–John Owen, The Holy Spirit and His Work in The Works of John Owen, ed. William Goold, 24 vols. (Edinburgh: Johnson & Hunter; 1850-1855; reprint by Banner of Truth, 1965), 3:27.
