2 Corinthians 2:5-11 ESV
Now if anyone has caused pain, he has caused it not to me, but in some measure-not to put it too severely-to all of you.  For such a one, this punishment by the majority is enough,  so you should rather turn to forgive and comfort him, or he may be overwhelmed by excessive sorrow.  So I beg you to reaffirm your love for him.  For this is why I wrote, that I might test you and know whether you are obedient in everything.  Anyone whom you forgive, I also forgive. Indeed, what I have forgiven, if I have forgiven anything, has been for your sake in the presence of Christ,  so that we would not be outwitted by Satan; for we are not ignorant of his designs.
Jesus came to forgive people for sins. As such we who are in Christ must fully be aware of our calling to forgiveness. Often we seek to do the work of the Holy Spirit which is in part to convict people of their sins. We also know that the Holy Spirit was sent to comfort. We know that if we do sin as we are still in flesh that we do have a advocacy in heaven according to John’s epistle. Always we must be feeding our spirit to be protected from those things the flesh still want to do. Daily in the word, daily praying. If we are in a spirit of unforgiving to ourselves or others we leave opening to Satan. Who do we forgive? Jesus asked the father to forgive those who were currently beating and going to murder him all the same as those who asked for forgiveness in his name. If We forgive he will forgive. If you do not look at anyones past you can be the light to the whole world and Satan has no cause to to show against you to those who are in sorrow.
Luke 23:34 ESV
And Jesus said, “Father, forgive them, for they know not what they do.” And they cast lots to divide his garments.
