Mark 11:23-25 AMPC
Truly I tell you, whoever says to this mountain, Be lifted up and thrown into the sea! and does not doubt at all in his heart but believes that what he says will take place, it will be done for him.
For this reason I am telling you, whatever you ask for in prayer, believe (trust and be confident) that it is granted to you, and you will [get it].
And whenever you stand praying, if you have anything against anyone, forgive him and let it drop (leave it, let it go), in order that your Father Who is in heaven may also forgive you your [own] failings and shortcomings and let them drop.
