But if anyone has caused grief, he has not done it to me [only], but to nearly all of you [or, "only partially to all of you"] for I do not want to overstate the case.

You people show [i.e., by your conversions] that you are a letter from Christ, delivered by us [i.e., the result of our ministry], not written with ink but with the Holy Spirit of the living God; not on stone tablets [i.e., as in the case with Moses' ministry], but on tablets of the human heart. [See Jer. 31:33; Heb. 8:10].

You people are looking [merely] at the appearance of things [or, "You should look at what is obvious!" In either case, it suggests they were misjudging Paul's ministry]. If any person is confident within himself that he belongs to Christ, he should reflect on this again: We are just as much Christ's [servants] as he is.
