“Faith is not content with ‘fleeting pleasures.’ It is ravenous for joy. And the Word of God says, ‘In Your presence there is fullness of joy; at Your right hand are pleasures forevermore’ (Psalm 16:11). So faith will not be sidetracked into sin. It will not give up so easily in its quest for maximum joy.
“The role of God’s Word is to feed faith’s appetite for God. And, in doing this, it weans my heart away from the deceptive taste of lust.
“At first, lust begins to trick me into feeling that I would really miss out on some great satisfaction if I followed the path of purity. But then I take up the sword of the Spirit and begin to fight. …
“As I pray for my faith to be satisfied with God’s life and peace, the sword of the Spirit carves the sugar coating off the poison of lust. I see it for what it is. And by the grace of God, its alluring power is broken.” —John Piper
