2 Corinthians 1:23-2:11
But I call God to witness against me -- it was to spare you that I refrained from coming to Corinth. Not that we lord it over your faith; we work with you for your joy, for you stand firm in your faith.
For I made up my mind not to make you another painful visit. For if I cause you pain, who is there to make me glad but the one whom I have pained? And I wrote as I did, so that when I came I might not suffer pain from those who should have made me rejoice, for I felt sure of all of you, that my joy would be the joy of you all. For I wrote you out of much affliction and anguish of heart and with many tears, not to cause you pain but to let you know the abundant love that I have for you. But if any one has caused pain, he has caused it not to me, but in some measure -- not to put it too severely -- to you all.
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. Any one whom you forgive, I also forgive. What I have forgiven, if I have forgiven anything, has been for your sake in the presence of Christ, to keep Satan from gaining the advantage over us; for we are not ignorant of his designs.
