Romans 12:10

Be, &c.--better, "In brotherly love be affectionate one to another; in [giving, or showing] honor, outdoing each other." The word rendered "prefer" means rather "to go before," "take the lead," that is, "show an example." How opposite is this to the reigning morality of the heathen world! and though Christianity has so changed the spirit of society, that a certain beautiful disinterestedness and self-sacrifice shines in the character of not a few who are but partially, if at all under the transforming power of the Gospel, it is only those whom "the love of Christ constrains to live not unto themselves," who are capable of thoroughly acting in the spirit of this precept.

The apostle, having at large cleared and confirmed the prime fundamental doctrines of Christianity, comes in the next place to press the principal duties. We mistake our religion if we look upon it only as a system of notions and a guide to speculation. No, it is a practical religion, that tends to the right ordering of the conversation.

We must first understand how we receive Christ Jesus the Lord, and then we shall know the better how to walk in him. There is a great deal of duty prescribed in this chapter. The exhortations are short and pithy, briefly summing up what is good, and what the Lord our God in Christ requires of us. It is an abridgment of the Christian directory, an excellent collection of rules for the right ordering of the conversation, as becomes the gospel. It is joined to the foregoing discourse by the word "therefore." It is the practical application of doctrinal truths that is the life of preaching. He had been discoursing at large of justification by faith, and of the riches of free grace, and the pledges and assurances we have of the glory that is to be revealed. Hence carnal libertines wou…
