The Bible calls us to discipline ourselves for godliness. There are many spiritual disciplines that we have as Christians, such as reading our Bibles or praying. There is one spiritual discipline that can be often overlooked, though, and that is the discipline of fasting. "But when you fast, put oil on your head and wash your face, so that it will not be obvious to others that you are fasting, but only to your Father, who is unseen; and your Father, who sees what is done in secret, will reward you." Matthew 6:17-18
