Fasting & Prayer is a biblical principle of the Kingdom of God. Biblical fasting is refraining from food for spiritual purposes. This takes a lot of discipline and strength. Let me illustrate it this way. If you decide to diet it will take a lot of discipline and it is the same way except that in fasting you spend these times of refraining from food to pray. We believe that as we pray and seek God and give Him our best, He will step into our lives and do touch us in ways we cannot imagine.
“As they were worshiping the Lord and fasting, the Holy Spirit said, “Set apart for me Barnabas and Saul for the work to which I have called them.”” (Act 13:2, CSB)
