Romans 12:3

For I say--authoritatively through the grace given unto me--as an apostle of Jesus Christ; thus exemplifying his own precept by modestly falling back on that office which both warranted and required such plainness towards all classes. to every man that is among you, not to think, &c.--It is impossible to convey in good English the emphatic play, so to speak, which each word here has upon another: "not to be high-minded above what he ought to be minded, but so to be minded as to be sober-minded" [CALVIN, ALFORD]. This is merely a strong way of characterizing all undue self-elevation. according as God hath dealt to every man the measure of faith--Faith is here viewed as the inlet to all the other graces, and so, as the receptive faculty of the renewed soul--that is, "as God hath given to each his particular capacity to take in the gifts and graces which He designs for the general good."

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. It is designed not only to inform our judgments, but to reform our hearts and lives. From the method of the apostle's writing in this, as in some other of the epistles (as from the management of the principal ministers of state in Christ's kingdom) the stewards of the mysteries of God may take direction how to divide the word of truth: not to press duty abstracted from privilege, nor privilege abstracted from duty; but let both go together, with a complicated design, they will greatly promote and befriend each other. The duties are drawn from the privileges, by way of inference. The foundation of Christian practice must be laid in Christian knowledge and faith. 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…

12:3 by the faith God has given us: Or by the faith God has given you; or by the standard of our God-given faith. Whether Paul is referring to the amount of faith each of us has been given or to the Christian faith that we all hold in common, we need to assess ourselves accurately by this measure and not be vain about the abilities God has given us.
