Mark 11:20-26 NAS
As they were
passing by in the morning, they saw the fig tree withered from the roots up.
Being reminded, Peter said to Him, "Rabbi, look, the fig tree which
You cursed has withered." And Jesus answered saying to them, "Have
faith in God. Truly I say to you, whoever says to this mountain, 'Be
taken up and cast into the sea,' and does not doubt in his heart, but
believes that what has says is going to happen, it will be granted
him. Therefore I say to you, all things for which you pray and ask,
believe that you have received them, and they will be granted
you. Whenever you stand praying, forgive, if you have anything
against anyone, so that your Father who is in heaven will also forgive you
your transgressions. But if you do not forgive, neither will your
Father who is in heaven forgive your transgressions."
