2 Cor. 2:9-11 (KJV) For to this end also did I write, that I might know the proof of you, whether ye be obedient in all things. To whom ye forgive any thing, I forgive also: for if I forgave any thing, to whom I forgave it, for your sakes forgave I it in the person of Christ; Lest Satan should get an advantage of us: for we are not ignorant of his devices.
When I read this the immediate context of verse 11 seemed to be verse 10. When I read it the following day I wasn't sure if Paul was referring to the man the church had put out of the church and had repented (v.9), or to that if the church does not forgive the repentant man (v.10) that this unforgiveness is one of the devices of Satan (v.11). Or maybe Paul is referring to both. Our own unforgiveness being a device of Satan sounds like it should follow from Scripture, especially after all of the places God commands us to forgive others who repent of the wrongs they have committed against us. But I am looking for a more solid argument one way or the other. Does anyone know of such an argument from respected sources?
I have checked a couple of commentaries: Calvin, Matthew Henry, George Whitfield, and am still unsure. A Google search shows a whole ton of articles saying unforgiveness is a device of Satan, but I don't recognize any of those sources.
