Giving up physical pleasures for a spiritual purpose is being led by the spirit and less by the body. It's fasting and then staying steadfast in the shifts you decided to make. Listen if you know there's more fruit in your spirit than in your body, vices and carnal wants.
If you are looking to fast to connect with God and believe that fasting and praying works, this episode is for you. If you need some motivation to break habits that no longer serve you, this episode is for you.
