In the cursed fig tree the Lord Jesus taught His apostles how to trust God by faith in their prayers. Prayer is a work, one of great difficulty at times. We are to labor fervently in our prayers. The apostles asked the Lord Jesus, "Teach us to pray." Jesus cursed the fig tree, and then referred to moving mountains, but Jesus wasn't teaching His disciples that they could literally move a mountain, but He was a saying, when you have an insurmountable problem before you, bring that problem to Me, saith Jesus! Come in faith, and I will move that mountain. But don't forget, in regard to your prayer, Thy will be done in earth, as it is in heaven."
