Romans 1:12

That is. With all Christian humility and courtesy Paul hastens to correct any impression he may have given by the statement in v. 11 that it is for him only to impart and for them only to receive. It is not his intention to “have dominion” over their faith (2 Cor. 1:24). He recognizes that his readers also are Christians, and he himself expects to be benefited by the sharing of a “mutual faith.”

Comforted. Or, “encouraged.” Verse 12 seems to be more than a mere expression of tact and courtesy. The experienced apostle joins himself with the believers at Rome as needing to be no less encouraged by their faith than they by his. Christian perfection is not to be found in seclusion or in isolation from others. It is developed as the faith of Christians is encouraged and stimulated by that of their fellow believers.
