For ye are dead,.... Not in a natural or corporeal sense, for they were living in the world; nor in a moral sense, for though they had been dead in sins, they were quickened by the grace of God; nor in a legal sense, for all their trespasses were forgiven them; see Col 2:13; but they were dead to the law, moral, ceremonial, and judicial, by the body of Christ; and to sin, as to its damning power, through his bearing it in his own body on the tree; and to the world by his cross: and therefore as dead men have nothing to do with the world, and the things of it, so believers being dead with Christ, should have no regard to the rudiments of the world, the ceremonies of the law, and the ordinances of men; to worldly lusts, and to the things that are in the world, the lust of the flesh, the lust of the eyes, and the pride of life; but should be dead as to their desires after, affections for, and subjection to these things:and your life is hid with Christ in God; which is another reason why they should not mind things on earth, but things in heaven.
The saint's "life" is either spiritual, and is a life of grace from Christ, a life of faith on him, and a life of communion with him, and may be distinguished into a life of sanctification, both internal and external, and into a life of justification; or eternal, which is a life free from all the sorrows of this, both outward and inward; a life of perfection and pleasure, of vision and enjoyment of God and Christ, and of fellowship with Father, Son, and Spirit, angels and saints, and which will never end.
This is "theirs", what they have a right unto, and shall everlastingly enjoy: it is not only promised to them, and prepared and laid up for them, but it is given unto them in Christ; and who has made way for their full possession of it, into which he himself will put them, having power, as Mediator, so to do; and even now they have it, the beginning, pledge, and earnest of it.
This is said to be "hid", which denotes the secrecy of it, and is true both of spiritual and eternal life. The spiritual life of the saints is hid from the men of the world, who are alienated from the life of God, are ignorant of the Lord of life, and know nothing of the spirit of life; they are strangers to the nature of this life, and to the food on which believers live, the hidden manna; and to the doctrines of the Gospel, by which they are nourished, these are hid to them that are lost; and to all the joys and pleasures of it: and this is sometimes hid from the saints themselves, when temptations are violent, corruptions prevail, grace is low, and seems to be gone, and God hides his face.
Eternal life is also an hidden one from natural men; the things that are eternal, are things unseen by the carnal eye, and not to be conceived of by a carnal heart; and can only be beheld, and that in a very glimmering and imperfect manner, by an eye of faith, which is the evidence of things not seen, the clearest one saints have in this life; for eternal glory and happiness is in part hid from the saints themselves; they see it but through a glass darkly; nor does it appear to themselves, as yet, what that felicity is in its fulness and perfection they shall enjoy.
Moreover, this phrase is expressive of the safety, as well as of the value and preciousness of this life, things of worth being hid for security. It is hid, and it is hid "with Christ"; spiritual life is with him, as the head, root, and fountain of it, and so is safe, and can never be lost; because he the head lives, the members shall live also; and as long as it is in him, as the fountain, the streams and supplies of it shall not be wanting to his people; nor can the communication between him and them be ever cut off: eternal life is deposited in his hands by the Father; it is bound up in the bundle of life with the Lord God, and is in him for ever safe: nay, it is not only with Christ, where it is secure enough, but it is with Christ "in God"; Christ is in God, the Father is in the Son, and the Son is in the Father; they are one in nature, and so in power and glory; and this union between them, which is natural and perfect, is the foundation of the security both of the persons, and of the life, spiritual and eternal, of God's elect; see Joh 10:28.
Moreover, this life itself is in God.
