Spiritual disciplines are not ways to eradicate all our desires but ways to order them so that they can serve one another and together serve God.
For further reflection...
"Delight yourself in the Lord and he will give you the desires of your heart. Commit your way to the Lord; trust in him and he will do this."
Psalm 37: 4-5 (NIV)
