Mark 11:22-26, "So Jesus answered and said to them, “Have faith in God. For assuredly, I say to you, whoever says to this mountain, ‘Be removed and be cast into the sea,’ and does not doubt in his heart, but believes that those things he says will be done, he will have whatever he says. Therefore, I say to you, whatever things you ask when you pray, believe that you receive them, and you will have them. “And whenever you stand praying, if you have anything against anyone, forgive him, that your Father in heaven may also forgive you your trespasses. But if you do not forgive, neither will your Father in heaven forgive your trespasses.”

Jesus gives us an incredible promise in Mark chapter 11; however, the power and authority we receive is on the foundation stone of forgiveness. If we want authority to move mountains, we must forgive.
