Fasting? Should Christians fast?

...The most significant Biblical characters, with the possible exception of Abraham, were all men of fasting and prayer. Jesus, the Son of God, was a man of fasting and prayer (Matthew 4:2). So was the apostle Paul (2 Corinthians 11:27). Moses fasted 80 days. Elijah fasted 40 days....God wants to do many amazing things, but He looks for those willing to urgently make the corrections needed to come into line with him. God resists the proud, but gives grace to the humble. Successful fasting is also the fastest way to learn patience.
This excerpt comes from an article called Fast - key to power where the author develops the view that fasting is pleasing to the Lord.

Maybe you are totally opposed to fasting, if so, tell us why. I would like to know what you think on this question. Do you fast? If yes, will you spare a moment and tell us why?
