Romans 15:14

And I myself also am persuaded of you, my brethren, that ye yourselves are full of goodness, filled with all knowledge, able also to admonish one another.

Just having devoted a large section of his letter to questions regarding the maintenance of unity and love in the congregation, Paul, in this verse, said with great tact and consideration that he believed the Christians in Rome were full of goodness and able to handle all such problems themselves without any special admonitions from him. Such a statement on Paul's part was doubtless for the purpose of avoiding any impression that he was critical of their congregations, or that he had been discoursing on the sins of a church which he had never seen. Furthermore, Paul's words here must be understood in the light of their being actually true and complimentary in a very high degree of the body of Christ in the great imperial capital, which never having enjoyed the visit Of an apostle, having come from various lands and provinces, and being a truly cosmopolitan group, had, nevertheless, maintained unity of the faith, not being deficient in any vital knowledge, and truly exhibiting all the virtues and graces of Christianity. One limitation of Paul's word regarding "all knowledge" was noted by Lenski, thus:

"All knowledge" does not mean all possible knowledge, nor does it suggest that the Romans had nothing more to learn; but that they had all necessary knowledge so that they could proceed safely and securely.[6]

I myself also ... shows that others had brought information to Paul regarding the Roman church and that the high opinion of such informants had been well attested to the extent that Paul was convinced of the truth of their favorable report of the Christians in Rome.

With this verse, the last section of the epistle begins, in which there are many things of a personal nature, including greetings from personal friends to personal friends in the great city. This section is full of interest.
