That thou appear not unto men to fast, but unto thy Father which is in secret: and thy Father, which seeth in secret, shall reward thee openly. Matthew 6:18 KJV
Fasting is a time of seeking God, His plan, and His purpose for our lives. It is a time to subdue our carnal nature and highten our spiritual acuity.
Fasting is not a time to show others how “spiritual” we are nor is it a time to satisfy our own estimation of self. In fact a true fast will reveal the areas that the Lord wants to remove or heal, and restore.
As in all things we do as a result of our relationship with God, our reward is in Him not in the acceptance or promotion of man. Fasting is between each individual and his Creator.
The benefits of this discipline are phenomenal.
