Have faith in God, Forgive to be forgiven

20 Now in the morning as they passed by, they saw the fig tree dried up from the roots.
21 And, Peter remembering said to Him, "Rabbi look! The fig tree which you cursed has withered away."
22 So Jesus answered and said to them, "have faith in God.
23 "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 believed that those things he says will be done, he will have whatever he says.
24 "Therefore I say to you, whatever things you ask for when you pray, believe that you will receive them, and you will have them.
25" And whenever you stand praying, if you have anything against anyone, forgive him, that your Father in heaven may also forgive you your trespasses.
26 "But if you do not forgive, neither will your Father in heaven forgive your trespasses"

-Mark 11 20:26
