Begin a fast, and trust God to work that in your heart.
Every deed has a seed. In other words, the deeds you choose to do in this lifetime create a seed for future generations.
If you want to please God, believe God.
Never speak words that allow the enemy to think he's winning.
Many times the rewards of fasting come after the fast, though from time to time answers can come during the fast.
The discipline of fasting breaks you out of the world's routine.
