After you have read verses 35-41 just back up one verse and read it again; V40; and He said unto them, why are you so fearful? how is it that ye have no faith? Because in Mark 11: 22; Jesus commanded us (His disciples) to have faith in God! Then He said, "Whosoever shall say unto this mountain, be thou removed……. the big words there are "WHOSOEVER, and have FAITH IN GOD" When you are threatened by dangerous situations speak to your mountains with God’s Faith!
Have a blessed day;
