Take these three spears!
(Thomas Watson, "The Mischief of Sin")
Do with your sin — as Joab did with Absalom. He took three spears and thrust them through the heart of Absalom! 2 Samuel 18:14. Just so, take these three spears — the Word of God, prayer, and mortification — and strike through the heart of your lusts, so that they die!
What is the end of all a Christian's duties, praying, and hearing — but to weaken and mortify lust! Why is this spiritual medicine taken — but to kill the child of sin! Sin will insinuate itself and plead for a reprieve — but show it no mercy!
Saul's sparing Agag lost him the kingdom — and your sparing sin will lose you the kingdom of Heaven. Do with your sin, what Samuel did to Agag, "He hacked Agag to pieces before the Lord at Gilgal." 1 Samuel 15:33
