If ye have heard of the dispensation of the grace of God,.... Not the free love and favour of God in his heart towards his people; nor internal grace wrought in the heart of the apostle; but either the gift of grace, as in Eph 3:7 qualifying him for the work of the ministry; and so the Ethiopic version renders it, "if ye have heard the gift of the grace of God"; or rather the doctrine of grace, the Gospel, the subject matter of which is the grace of God; it is a declaration of the free grace of God in the salvation of men; and it is the means of conveying the grace of God into their hearts.
Now the apostle had a dispensation to preach this Gospel committed to him; he acted by authority, and as a steward of the mysteries of God; and which he faithfully dispensed to the family of Christ, who appointed him to this service: this the Ephesians had heard of, from the relations of the apostle, and others, and knew it themselves, having often heard him preach, for he was with them for the space of three years; wherefore this is not said as if he questioned, whether they had heard or not, but as taking it for granted that they had: "if", or "seeing ye have heard", &c.
