When a lost sinner is truly under conviction, he will see the folly and evil of unbelief; he will confess that he does not measure up to the righteousness of Christ; and he will realize that he is under condemnation because he belongs to the world and the devil (Eph. 2:1–3). Th ere can be no conversion without conviction, and there can be no conviction apart from the Spirit of God using the Word of God and the witness of the child of God. Warren W. Wiersbe, The Bible Exposition Commentary, vol. 1 (Wheaton, IL: Victor Books, 1996), 362.
