Fasting, eating nothing, is unthinkable right? As a health experiment I recently took up fasting several days a week. It has been a revelation. I've discovered more time and energy to focus on God. In deprivation I have found a profound gratitude to God for giving me life. (See link below to BBC documentary.)

Matthew 6:17-18
But when you fast, anoint your head and wash your face,
that your fasting may not be seen by others but by your Father who is in secret. And your Father who sees in secret will reward you.
