Romans 15:14
Nestle 1904 Greek New Testament · Berean Standard Bible
Πέπεισμαι δέ ἀδελφοί μου καὶ αὐτὸς ἐγὼ περὶ ὑμῶν ὅτι καὶ αὐτοὶ μεστοί ἐστε ἀγαθωσύνης πεπληρωμένοι πάσης τῆς γνώσεως δυνάμενοι καὶ ἀλλήλους νουθετεῖν
I myself am convinced, my brothers, that you yourselves are full of goodness, brimming with knowledge, and able to instruct one another.
