It is important that we examine ourselves humbly before God, and that should be a continual process.   One of the most powerful disciplines that God provides for us to remain humble before Him is fasting.  Fasting is not an undertaking that we should do only once a year when commanded by God, or a day beore Passover out of necessity.  Rather, fasting should be done OFTEN to help support our continual state of Godly humility, spiritual development, and spiritual growth to draw close to God and become more like Him.
