only sins against you. you cannot forgive anyone for sins that don't involve you. you can only speak for yourself and trespasses against you. you have not been given power or authority to forgive a murderer or any sinner; you can only do that in your mind. the sinner is forgiven because of Christ; not you -
I said
I don't think you even understand the verse. If we are going to be Christians we must forgive everyone of sin. Or WE will not be forgiven.
