From Søren Kierkegaard’s "Works of Love"

"If honestly before God you wholeheartedly forgive your enemy . . . then you may also dare to hope for your forgiveness, because they are one and the same. God forgives you neither more nor less nor otherwise than as you forgive those who have sinned against you. It is only an illusion to imagine that one oneself has forgiveness although one is reluctant to forgive others . . . It is also a delusion to believe in one’s own forgiveness when one refuses to forgive, for how could a person truly believe in forgiveness if his own life is an objection against the existence of forgiveness!"
. . .
"God will do unto you exactly as you do unto others. In the Christian sense, you have nothing at all to do with what others do unto you – it does not concern you; it is a curiosity, an impertinence, a lack of good sense on your part to meddle in things that are absolutely no more your concern than if you were not present. You have to do only with what you do unto others, or how you take what others do unto you. The direction is inward; essentially you have to do only with yourself before God."
