And I myself also am persuaded of you, my brethren, that ye yourselves also are full of goodness, filled with all knowledge, able also to admonish one another. It is St. Paul's courteous as well as kindly way to compliment those to whom he writes on what he believes to be good in them, and to cling to a good opinion of them, even where he has some misgivings, or has had reason to find fault (cf.
1 Corinthians 1:4, seq.; 2 Corinthians 1:7; 2 Corinthians 3:1, seq.; 2 Corinthians 7:3, seq.). Here "I myself also" ( καὶ αὐτὸς ἐγὼ) may have tacit reference to the general good report of the Roman Church (cf.
Romans 1:8 and Romans 16:19), which he means to say he himself by no means doubts the truth of, notwithstanding his previous warnings. "Ye yourselves also" ( καὶ αὐτοὶ) implies his trust that even without such warnings they would of themselves be as he would wish them to be; "full of goodness" ( ἀγαθωσύνης), so as to be kind to one another, as they were enlightened and replete with knowledge ( γνώσεως).
