2 Corinthians 7:12 Wherefore, though I wrote unto you, I did it not for his cause that had done the wrong, nor for his cause that suffered wrong, but that our care for you in the sight of God might appear unto you.

The Apostle Paul had the well-being of the Corinthian church in mind when he wrote to them. This is well expressed in 2 Corinthians 2:3-4 And I wrote this same unto you, lest, when I came, I should have sorrow from them of whom I ought to rejoice; having confidence in you all, that my joy is the joy of you all. For out of much affliction and anguish of heart I wrote unto you with many tears; not that ye should be grieved, but that ye might know the love which I have more abundantly unto you.
