Mark 11:25
And whenever you stand praying, forgive, if you have anything against anyone, so that your Father also who is in heaven may forgive you your trespasses.
If I desire forgiveness, that is the complete removal of all negative karma in my life which are obstacles like a big mountain, I must not cling to thoughts of anger, hatred and jealousy in my mind.
Because I for my part do not desire God’s anger, but his certain loving compassion in forgiving me, just so I too must be compassionate to others. How else can he forgive me?
As for a hating man or a sorcerer, God will certainly not clear his sins.
