Okay. So, if the offender is dead, and cannot apologize, then, forgiveness must not be given. VP, HW, EO, and DDW are all dead. Even if they wanted to request your forgiveness after an apology, they cannot do it, and according to your doctrine, you are not allowed to forgive and therefore you must go on through life in a state of "unforgiveness" (it's called holding a grudge in the common vernacular), and leave your self open to self destructive bitterness. Forgiveness is not just about the one being forgiven. Forgiveness is also about the healing of the one doing the forgiving.
Jesus forgave his murderers and yet they still mocked him until the end.
"Forgive them Father for they know not what they do."
"Looking unto Jesus the author and finisher of our faith; who for the joy that was set before him endured the cross, despising the shame, and is set down at the right hand of the throne of God. For consider him that endured such contradiction of sinners against himself, lest ye be wearied and faint in your minds". Hebrews
Yes, I prefer to consider him, and follow after him who forgave those who mocked him beat him, spit in his face, tortured him physically, "made sport of him", pounded a crown of thorns on his head (into his head) and then nailed his bloodied near corpse to the cross and further mocked him. And he goes on to say; Forgive them Father for they know not what they do."
Well, that's good enough for me. Why not for some of you? As Chatty Kathy used to say around here, "some of you here have spent more time revisiting The Way (and have it still swirling about in your head!) than the time you actually spent in The Way!"
Look none of us have endured anything near what our Lord Jesus Christ endured. And he was INNOCENT! We, on the other hand are/were not innocent. We, who gleefully went about snorkeling in the cess pools of sin and iniquity without a trace of guilt for many of us were far from innocent. But Jesus was actually and entirely innocent and he forgave those who hurt hi, who wronged him.
Therefore it behooves us even more to follow his example and forgive those who have trespassed against us. Shoot, LCM tried to seduce my wife when he was married and she single. She nailed him with "It Is Written", and he backed off. He's never apologized to her, but she has forgiven him. As have I. I would never trust him again, but I forgive him...
