2 Corinthians 7:16

‘I rejoice that in everything I am of good courage concerning you.'

Thus Paul himself rejoices in that he is assured in his heart concerning them in every way.

So ends this section of his letter, a combination of rejoicing over their response, which is how it finishes, yet including the clear indication of his fears that nevertheless there was much still to be put right, not mainly in regard to their response to him, although there is some question about some, but with regard to their daily living and their attitudes to life. They have a need for a closer identification with Christ in His death and resurrection, a more complete separation of themselves to God, a releasing of themselves from the yoke of the idolatrous world, and an avoidance of such things as can hinder their love for Him (2 Corinthians 6:14), and then they will see Him fully, with the veil removed (2 Corinthians 3:18), and will become more like Him day by day.

Sadly it was not to be long before news reached him that somewhat altered his confidence, even before he had completed the letter (10--13).
