Great post.
You might be interested to know that fasting with prayer has been a form of spiritual enlightenment and strengthening since Old Testament times. In The Church of Jesus Christ of Latter-day Saints, members observe a monthly 24 hour fast for these purposes. Also it is used as a way to care for the poor or needy. The money we would have spent on the meals that we fast for, is donated to the Church which is collectively used to help those in need. Each month in South Africa alone many thousands of Rands are raised every month and distributed.
The health and spiritual benefits are enjoyed by those who fast. It is usually the first Sunday of each month that we fast and it is sometimes the most enjoyable of Sundays in the month.
Anyway, well done.
