Having then gifts, differing,.... As in a natural body, the various members of it have not the same office, and do not perform the same actions, thus they have not the same, but different faculties; one has one faculty, another another; the eye has the faculty of seeing, the ear of hearing, &c.
thus in the spiritual body the church, as there are different members, these members have not the same work and business assigned them; some are employed one way, and some another; also they have diversities of gifts for their different administrations and operations, and all from Christ their head, by the same Spirit, and for the service of the whole body,according to the grace that is given unto us; for all these gifts are not the effects of nature, the fruits of human power, diligence, and industry, but flow from the grace of God, who dispenses them when, where, and to whom he pleases in a free and sovereign manner; and therefore to be acknowledged as such, and used to his glory, and for the good of his church and people.
Whereforewhether prophecy, [let us prophesy] according to the proportion of faith. The offices here, and hereafter mentioned, are not of an extraordinary, but ordinary kind, such as are lasting, and will continue in the church unto the end of time: and are divided into two parts, which are after subdivided into other branches.
The division is into "prophesying" and "ministering". By "prophesying" is meant, not foretelling things to come, thought this gift was bestowed upon some, as Agabus, and others in the Christian church; but this, as it is of an extraordinary nature, so it is not stinted and limited according to the proportion of faith; but preaching the Gospel is here designed, which is the sense of the word in many places of Scripture, particularly in 1Co 13:2.
Now such who have this gift of prophecy, or of opening and explaining the Scriptures, ought to make use of it, and constantly attend toil: "let us prophesy"; diligently prepare for it by prayer, reading and meditation, and continually exercise it as opportunity offers; nor should any difficulty and discouragement deter from it: or whereas this last clause is not in the original text, it may be supplied from Ro 12:3; thus, "let us think soberly", who have this gift, and not be elated with it, or carry it haughtily to those who attend on the exercise of it: but behave with sobriety, modesty, and humility, in the discharge thereof: "according to the proportion of faith".
There must be faith, or no prophesying; a man must believe, and therefore speak, or speak not at all; a Gospel minister ought not to be a sceptic, or in doubt about the main principles of religion; such as concern the three divine persons, the office, grace, and righteousness of Christ, and the way of salvation by him: he should be at a point in these things, should firmly believe, and with assurance assert them, nor fear to be called dogmatical on that account: he is to preach according to his faith, the proportion of it: which may be the same with the measure of it, Ro 12:3.
