They went forth, and preached every where, the Lord working with them, and confirming the Word with signs following.  –Mark 16:20 (KJV)

When Ahab saw him, he exclaimed, “So, is it really you, you troublemaker of Israel?” “I have made no trouble for Israel,” Elijah replied. “You and your family are the troublemakers, for you have refused to obey the commands of the Lord and have worshiped the images of Baal instead.”  –1 Kings 18:17-18 (NLT)

Backslidden Christians will be brought to repentance. A revival is nothing else than a new beginning of obedience to God. Just as in the case of a converted sinner, the first step is a deep repentance, a breaking down of heart, a getting down into the dust before God, with deep humility, and forsaking of sin. –Charles Finney
