Romans 12:1

We may observe here, according to the scheme mentioned in the contents, the apostle's exhortations, I. Concerning our duty to God, We see what is godliness. 1. It is to surrender ourselves to God, and so to lay a good foundation. We must first give our own selves unto the Lord, Co2 8:5. This is here pressed as the spring of all duty and obedience, Rom 12:1, Rom 12:2. Man consists of body and soul, Gen 2:7; Ecc 12:7. (1.) The body must be presented to him, Rom 12:1. The body is for the Lord, and the Lord for the body, Co1 6:13, Co1 6:14. The exhortation is here introduced very pathetically: I beseech you, brethren. Though he was a great apostle, yet he calls the meanest Christians brethren, a term of affection and concern. He uses entreaty; this is the gospel way: As though God did beseech you by us, Co2 5:20. Though he might with authority command, yet for love's sake he rather beseeches, Plm 1:8, Plm 1:9. The poor useth entreaty, Pro 18:23. This is to insinuate the exhortation, that it might come with the more pleasing power. Many are sooner wrought upon if they be accosted kindly, are more easily led than driven. Now observe, [1.] The duty pressed - to present our bodies a living sacrifice, alluding to the sacrifices under the law, which were presented or set before God at the altar, ready to be offered to him.
