| Geneva Study Bible {4} For as we have many members in one body, and all members have not the same office: (4) There are two reasons for the previous precept: the first is because God has not committed everything to be done by every man: and therefore he does backwardly, and unprofitably, and also to the great disservice of others, wearying himself and others, who passes the bounds of his calling: the second is because this diversity and inequality of vocations and gifts results in our being benefitted: seeing that this is therefore instituted and appointed, so that we should be bound one to another. From which it follows that no man ought to be grieved at this, seeing that the use of every private gift is common. People's New Testament 12:4 For as we have many members in one body. The church is likened to the human body in which the various organs each has its own office. Jamieson-Fausset-Brown Bible Commentary 4, 5. For as we have many members, &c.-The same diversity and yet unity obtains in the body of Christ, whereof all believers are the several members, as in the natural body. Matthew Henry's Concise Commentary 12:3-8 Pride is a sin in us by nature; we need to be cautioned and armed against it. All the saints make up one body in Christ, who is the Head of the body, and the common Centre of their unity. In the spiritual body, some are fitted for and called to one sort of work; others for another sort of work. We are to do all the good we can, one to another, and for the common benefit. If we duly thought about the powers we have, and how far we fail properly to improve them, it would humble us. But as we must not be proud of our talents, so we must take heed lest, under a pretence of humility and self-denial, we are slothful in laying out ourselves for the good of others. We must not say, I am nothing, therefore I will sit still, and do nothing; but, I am nothing in myself, and therefore I will lay out myself to the utmost, in the strength of the grace of Christ. Whatever our gifts or situations may be, let us try to employ ourselves humbly, diligently, cheerfully, and in simplicity; not seeking our own credit or profit, but the good of many, for this world and that which is to come. |
