In the morning, as he was returning to the city, he became hungry. And seeing a fig tree by the wayside, he went to it and found nothing on it but only leaves. And he said to it, “May no fruit ever come from you again!” And the fig tree withered at once. When the disciples saw it, they marveled, saying, “How did the fig tree wither at once?” And Jesus answered them, “Truly, I say to you, if you have faith and do not doubt, you will not only do what has been done to the fig tree, but even if you say to this mountain, ‘Be taken up and thrown into the sea,’ it will happen. And whatever you ask in prayer, you will receive, if you have faith.”
This is certainly one of the oddest passages in the gospels. It is hard to explain why Jesus spoke to the fig tree in such a fashion. Even so, the Lord uses this to speak to the disciples about faith. Speaking in hyperbolic language he tells them of how faith can move mountains. Some misunderstand these verses and interpret them literally implying that faith is all about 'speaking' to the mountains in our lives.
Jesus clarifies the mountain moving passage and puts it in the context of prayer. Interesting how he connects faith and prayer. One might think that prayer itself is an evidence of prayer - why would some one pray if they did not have faith? I think that some pray with a motive of fear or worry instead of faith - their heart cannot see or embrace an answer. To these Jesus says you will receive - if you have faith.
I lay down my cares, fears and worries Lord. I hope in you. Help my heart to believe.
