Romans 1:13

Not have you ignorant. A favorite expression with Paul when he wishes to call special attention to some important point (see Rom. 11:25; 1 Cor. 10:1; 12:1; 2 Cor. 1:8; Thess. 4:13).

Let. That is, hindered or prevented. “Let” had this meaning when the KJV translation was made. Paul gives further evidence of the sincerity of his desire to visit the church at Rome. It had been not only his wish but often his definite purpose to see them (Acts 19:21). But in one way or another he had been prevented from making the journey (Rom. 15:22; cf. 1 Thess. 2:18; Acts 16:6, 7).

Have some fruit. Paul hoped to reap some harvest among them of men brought to a knowledge of Christ or to an increase of faith and good works. Jesus had directed His disciples to “go and bring forth fruit,” in their own lives and in the lives of others (John 15:16; cf. John 4:36). “Fruit” is a common figure of speech in the NT. Paul uses it to represent both good and bad results (Rom. 6:21, 22; 7:4, 5; Gal. 5:22; Phil. 1:22; 4:17; Col. 1:6).

Gentiles. Or, “nations” (see on v. 5). The words “among you also, even as among other Gentiles” suggest that the church at Rome was predominantly Gentile in its origin.
