WHY SHOULD I FAST?
The main point of fasting is to focus your attention on God. It provides that focus in a few ways:
The time and effort normally spent cooking and eating can be spent on prayer or meditation instead.
When you fast, you get hungry. That hunger serves as a reminder of why you are fasting, keeping it top-of-mind. Every time you feel hunger when fasting, use that as a prompt to pray.
Fasting can help us focus on the Giver instead of His gifts. Food is a gift form God, but how often do we fully appreciate God's goodness in how He provides everything we need? Going without food makes you more appreciative of both the gift and the Giver.
