Jesus spent 40 days fasting and praying to get ready for His ministry. Jesus is our example. In Luke 9:23, Jesus says, "If any man would come after me, let him deny himself, and take up his cross daily, and follow me" (ASV).
What obstacles are in front of you? What is God calling you to do with your time, talents, and resources? Why not consider taking one day to fast and pray and see what God does.
