For he that is called in the Lord,.... Which is to be understood, not of any civil calling, or of calling to an office; or of the outward call by the ministry of the word only; but of an internal, special, powerful, evangelical, and saving call by the grace of God; which is of persons out of darkness into light, out of bondage into liberty, from their sinful companions to the company and society of Christ and his people, from off themselves and their own righteousness, to the grace and righteousness of Christ, and out of the world unto a kingdom and glory.
And this may be said to be, in the Lord; either because it is by him, he is the efficient cause of it, his grace the moving cause, and his glory the end; or because it is in consequence of being in him, united to him, persons are first in the Lord, and then called by him; or because they are called into fellowship and communion with him; the whole is true, and make up the sense of the text; for he that is effectually called by grace, is called by the Lord, and by virtue of being chosen in him, and in union to him, and to partake of all the blessings of grace and glory that are with him.
