Fasting is a way for me to renew my spiritual hunger and regain my spiritual strength. For me this is key to maintaining victory over Satan and his temptations to love this world more than God. Fasting is how I allow the cravings of my flesh to be disciplined and brought under control. When I fast and pray I get clarity about the things that God wants me to have and release my desires for the things of this world.
The desires of this world anchor down the soul-they oppress the spirit. But pleasing God is truly what pleases me AND it leads to eternal life. Sin leads to death and separation from God. Fasting helps me make that choice clear.
