1:16 For I am not ashamed of the gospel - To the world, indeed, it is folly and weakness, 1Cor 1:18; therefore, in the judgment of the world, he ought to be ashamed of it; especially at Rome, the head and theatre of the world. But Paul is not ashamed, knowing it is the power of God unto salvation to every one that believeth - The great and gloriously powerful means of saving all who accept salvation in God's own way. As St. Paul comprises the sum of the gospel in this epistle, so he does the sum of the epistle in this and the following verse . Both to the Jew, and to the gentile - There is a noble frankness, as well as a comprehensive sense, in these words, by which he, on the one hand, shows the Jews their absolute need of the gospel; and, on the other, tells the politest and greatest nation in the world both that their salvation depended on receiving it, and that the first offers of it were in every place to be made to the despised Jews.

There were plenty of imperfect Christians amongst them; many things to rebuke; much …

Paul's Longing
'I long to see you, that I may impart unto you some spiritual gift, to the end ye may be established; 12. That is, that I may be comforted together with you, by the mutual faith both of you and me.'--ROMANS i. 11, 12. I am not wont to indulge in personal references in the pulpit, but I cannot but yield to the impulse to make an exception now, and to let our happy circumstances mould my remarks. I speak mainly to mine own people, and I must trust that other friends who may hear or read my words will …

Sin in the Heart the Source of Error in the Head
ROMANS i. 28.--"As they did not like to retain God in their knowledge, God gave them over to a reprobate mind." In the opening of the most logical and systematic treatise in the New Testament, the Epistle to the Romans, the apostle Paul enters upon a line of argument to demonstrate the ill-desert of every human creature without exception. In order to this, he shows that no excuse can be urged upon the ground of moral ignorance. He explicitly teaches that the pagan knows that there is one Supreme …
