Adam Clarke on Ephesians 4:7

Unto every one of us is given grace - Grace may here signify a particular office; as if the apostle had said: Though we are all equal in the respects already mentioned, yet we have all different offices and situations to fill up in the Church and in the world; and we receive a free gift from Christ, according to the nature of the office, that we may be able to discharge it according to his own mind. So the free gift, which we receive from Christ, is according to the office or function which he has given us to fulfill; and the office is according to that free gift, each suited to the other.
