And when you pray, do not heap up empty phrases as the Gentiles do, for they think that they will be heard for their many words. Do not be like them, for your Father knows what you need before you ask him.
(Matthew 6:7-8 ESV)

On the following day, when they came from Bethany, he was hungry. And seeing in the distance a fig tree in leaf, he went to see if he could find anything on it. When he came to it, he found nothing but leaves, for it was not the season for figs. And he said to it, “May no one ever eat fruit from you again.” And his disciples heard it.
(Mark 11:12-14 ESV)
Consider what happened within Jesus before his words escaped from His lips. Try to get a mental picture of what He through before you try to guess about what came out of His mouth.
And Peter remembered and said to him, “Rabbi, look! The fig tree that you cursed has withered.” And Jesus answered them, “Have faith in God. Truly, I say to you, whoever says to this mountain, ‘Be taken up and thrown into the sea,’ and does not doubt in his heart, but believes that what he says will come to pass, it will be done for him. Therefore I tell you, whatever you ask in prayer, believe that you have received it, and it will be yours. And whenever you stand praying, forgive, if you have anything against anyone, so that your Father also who is in heaven may forgive you your trespasses.” (Mark 11:21-25 ESV)
