” ‘Have faith in God,’ answers Jesus” when Peter points out the fig tree withered due to being cursed by the Lord. Jesus continues, ” ‘ I tell you the truth, if anyone says to this mountain, ‘Go, throw yourself into the sea,’ and does not doubt in his heart but believes that what he says will happen, it will be done for him.’ ”
Having complete faith in God, total trust in Him, total commitment to His authority leads to “impossible” prayers, requests, happenings. However, reading Jesus’ statement about commanding a mountain to throw itself into the sea results, in my mind, in incredulity — for one thing, why would I want a mountain to move into the sea? What would be the point of such a request? Sometimes, I think Jesus may be saying, “Yes, you can ask for such a worthless thing as moving a mountain into the sea and it will be done if you have no doubts; but remember, if God is willing to do such a valueless act for you, at your request, imagine what better acts He is willing to do for you and through you.”
James says, “When [you] ask, [you] must believe and not doubt, because he who doubts is like a wave of the sea, blown and tossed by the wind.” (James 1:6) You will not receive anything of God if doubt is harbored in your heart.
When you ask, ask with right motives. With faith in your heart, it will be done for you.
