Charles Ellicott Commentary 2 Corinthians 7:4

"Great is my boldness of speech toward you, great is my glorying on your behalf: I am filled with comfort, I overflow with joy in all our affliction." — 2 Corinthians 7:4 (ASV)

Great is my boldness of speech.—The context shows that he is not apologizing for bold and plain speaking, but uses the word as implying confidence (1 Timothy 3:13; Philemon 1:8). He can speak without reticence now, because he is going to express his comfort and joy at what had been reported to him.

I am exceeding joyful.—Literally, I exceedingly abound (or, overflow) in joy. The verb is the same as in Romans 5:20, and answers to the pressed above measure which he had used in 2 Corinthians 1:8, in speaking of his troubles.
