The believer is sanctified through and in Christ; and it is his sanctification in Him which is the source of all practical holiness. He is holy; and therefore is to be “holy in all manner of conversation.” This principle has ever been the same. God has separated from existing evil to Himself, and then given a variety of directions to keep the so separated person in practical separation. (See, as to Israel's sanctification, Lev. 20:24-26.) Sanctification now, is God's separation of individuals from the world unto Himself in Christ, so that the so separated are no more of the world, even as Christ is no more of the world, for they are in Him, as risen.
