Romans 1:8

I thank In the very entrance of this one epistle are the traces of all spiritual affections, but of thankfulness above all, with the expression of which almost all Paul's epistles begin; my God This word expresses faith, hope, love, and consequently all true religion; through Jesus Christ The gifts of God all pass through Christ to us; and all our petitions and thanksgivings pass through Christ to God: for you all, that your faith is spoken of By this term faith, the apostle expresses either the whole of Christianity, as Colossians 1:3, &c, or some branch of it, as Galatians 5:22. And in the beginning of his epistles he generally subjoins to the apostolic benediction a solemn thanksgiving for the faith, or for the faith, love, patience, and other graces of the brethren to whom he wrote, to make them sensible of their happy state, and to lead them to a right improvement of the advantages which they enjoyed as Christians. Throughout the whole world The faith of these Romans, being faith in the Lord Jesus as the Son of God, the Messiah expected by the Jews, and in the living and true God through him, included, of course, their turning from every species of idolatry; an event which could not fail to be spoken of with wonder through the whole empire, as there were multitudes of strangers continually coming to Rome from the provinces, who, on their return home, would report what they had seen. This event would be especially made the subject of conversation in the churches everywhere, through all parts of the empire, it being matter of joy to them all that the religion of Christ was professed in the imperial city, more especially as it was a most happy presage of the general spread of their holy religion; the conversion of the Romans encouraging the inhabitants of other cities to forsake the established idolatry, and turn to God. And, indeed, the wisdom and goodness of God established faith in the chief cities, in Jerusalem and in Rome particularly, that from thence it might be diffused to all nations. Add to this, that Rome being the metropolis of the world, the conversion of so many of its inhabitants brought no small credit to the evidences of the gospel.
