Mark 11:23-25

Listen to the truth I speak to you: Whoever says to this mountain with great faith and does not doubt, ‘Mountain, be lifted up and thrown into the midst of the sea,’ and believes that what he says will happen, it will be done. This is the reason I urge you to boldly believe for whatever you ask for in prayer—be convinced that you have received it and it will be yours. And whenever you stand praying, if you find that you carry something in your heart against another person, release him and forgive him so that your Father in heaven will also release you and forgive you of your faults.
