Mark 11:24 in the King James Version
Therefore I say unto you, What things soever ye desire, when ye pray, believe that ye receive them, and ye shall have them.
Context
23 For most certainly I tell you, whoever may tell this mountain, ‘Be taken up and cast into the sea,’ and doesn’t doubt in his heart, but believes that what he says is happening, he shall have whatever he says.
24 Therefore I tell you, all things whatever you pray and ask for, believe that you have received them, and you shall have them.
25 Whenever you stand praying, forgive, if you have anything against anyone; so that your Father, who is in heaven, may also forgive you your transgressions.
