Therefore I urge you, brethren, by the mercies of God, to present your bodies a living and holy sacrifice, acceptable to God, which is your spiritual service of worship. And do not be conformed to this world, but be transformed by the renewing of your mind, so that you may prove what the will of God is, that which is good and acceptable and perfect. For through the grace given to me I say to everyone among you not to think more highly of himself than he ought to think; but to think so as to have sound judgment, as God has allotted to each a measure of faith. For just as we have many members in one body and all the members do not have the same function, so we, who are many, are one body in Christ, and individually members one of another. Since we have gifts that differ according to the grace given to us, each of us is to exercise them accordingly: if prophecy, according to the proportion of his faith; if service, in his serving; or he who teaches, in his teaching; or he who exhorts, in his exhortation; he who gives, with liberality; he who leads, with diligence; he who shows mercy, with cheerfulness. Let love be without hypocrisy. Abhor what is evil; cling to what is good. Be devoted to one another in brotherly love; give preference to one another in honor; not lagging behind in diligence, fervent in spirit, serving the Lord; rejoicing in hope, persevering in tribulation, devoted to prayer, contributing to the needs of the saints, practicing hospitality. Bless those who persecute you; bless and do not curse. Rejoice with those who rejoice, and weep with those who weep. Be of the same mind toward one another; do not be haughty in mind, but associate with the lowly. Do not be wise in your own estimation. Never pay back evil for evil to anyone. Respect what is right in the sight of all men. If possible, so far as it depends on you, be at peace with all men. Never take your own revenge, beloved, but leave room for the wrath of God, for it is written, "VENGEANCE IS MINE, I WILL REPAY," says the Lord. "BUT IF YOUR ENEMY IS HUNGRY, FEED HIM, AND IF HE IS THIRSTY, GIVE HIM A DRINK; FOR IN SO DOING YOU WILL HEAP BURNING COALS ON HIS HEAD." Do not be overcome by evil, but overcome evil with good.
Can there be a better way to express the patient service of one Christian to another that is expected of us? I do not know what more I could add to this passage that would not be a simple restating of these words. I would like to call your attention to our call to perseverance in times of trouble and the calls to humility. We ought not to ever esteem ourselves in high estimation greater what we truly are. As well, we ought to use our gifts in the service of others according to the grace we have been given. In this I believe it is important to recognize two messages. Once message tells us that we should not try to save the world single-handedly, but understand our weaknesses. On the other hand, we also must realize our strengths, and recognize the gifts we have been given in their full state (which is often much higher and greater than we think), and we must use these gifts to their fullest.
Other than these small points, this passage is the most concise and clear message that could be given on this topic, I think.
