1:27-30 Those who profess the gospel of Christ, should live as becomes those who believe gospel truths, submit to gospel laws, and depend upon gospel promises. The original word conversation denotes the conduct of citizens who seek the credit, safety, peace, and prosperity of their city. There is that in the faith of the gospel, which is worth striving for; there is much opposition, and there is need of striving. A man may sleep and go to hell; but he who would go to heaven, must look about him and be diligent. There may be oneness of heart and affection among Christians, where there is diversity of judgment about many things. Faith is God's gift on the behalf of Christ; the ability and disposition to believe are from God. And if we suffer reproach and loss for Christ, we are to reckon them a gift, and prize them accordingly. Yet salvation must not be ascribed to bodily afflictions, as though afflictions and worldly persecutions deserved it; but from God only is salvation: faith and patience are his gifts.

27. Only—Whatever happens as to my coming to you, or not, make this your one only care. By supposing this or that future contingency, many persuade themselves they will be such as they ought to be, but it is better always without evasion to perform present duties under present circumstances [Bengel].

let your conversation be—(Compare Php 3:20). The Greek implies, "Let your walk as citizens (namely, of the heavenly state; 'the city of the living God,' Heb 12:22, 'the heavenly Jerusalem,' 'fellow citizens of the saints,' Eph 2:19) be," &c.

I … see … hear—so Php 1:30. "Hear," in order to include both alternatives, must include the meaning know.

your affairs—your state.

in one spirit—the fruit of partaking of the Holy Spirit (Eph 4:3, 4).

with one mind—rather as Greek, "soul," the sphere of the affections; subordinate to the "Spirit," man's higher and heavenly nature. "There is sometimes natural antipathies among believers; but these are overcome, when there is not only unity of spirit, but also of soul" [Bengel].

striving together—with united effort.
