Fasting can be an expression of finding your greatest pleasure and enjoyment in life from God. That’s the case when disciplining yourself to fast means that you love God more than food, that seeking Him is more important to you than eating. This honors God and is a means of worshiping Him as God. It means that you stomach isn’t your god as it is with some (Philippians 3:19). Instead it is God’s servant, and fasting proves it because you’re willing to sublimate its desires to those of the Spirit.
