Mark 11:24-25

24For this reason I am telling you, whatever things you ask for in prayer [in accordance with God’s will], believe [with confident trust] that you have received them, and they will be given to you.

25Whenever you stand praying, if you have anything against anyone, forgive him [drop the issue, let it go], so that your Father who is in heaven will also forgive you your transgressions and wrongdoings [against Him and others].
