"I’ve learned by experience that many Christians cannot distinguish the promptings of the Holy Spirit from the accusations of Satan. The difference is this: The Holy Spirit convicts us for sins that we have been unwilling to face in God’s presence; Satan makes us feel guilty for sins that are already under the blood of Christ — that is, for sins that we have already confessed. The Holy Spirit reminds us of our sins before we are cleansed; Satan continues to remind us of them after we are cleansed."
~Erwin Lutzer in the December 5, 2009 devotional reading from Our Journey
