Fasting is not only important but it is essential to walking with God to fulfill the purpose He has for you. 21 days of fasting is what it takes to bring deliverance to your entire bloodline. It holds the power to break generational curses. Fasting helps to weaken your fleshly desires so the seeds that God is planting in your life can ultimately strengthen you. When we fast and pray we need to be in expectation that God is going to meet us at our need. However, we need to be willing to surrender our battles to Him and recognize that He is our Deliverer.
