Who alone hath immortality Paul labors to demonstrate that there is no happiness, no dignity or excellence, no life, out of God. Accordingly, he now says that God alone is immortal, in order to inform us, that we and all the creatures do not, strictly speaking, live, but only borrow life from Him. Hence it follows that, when we look up to God as the fountain of immortal life, we should reckon this present life as of no value. But it is objected, that the human soul and angels have their immortality, and therefore this cannot be truly affirmed of God alone. I reply, when it is said, that God alone possesses immortality, it is not here denied that he bestows it, as he pleases, on any of his creatures. The meaning is the same as if Paul had said that God alone is immortal from himself and from his own nature, but has immortality in his power; so that it does not belong to creatures, except so far as he imparts to them power and vigor; for if you take away the power of God which is communicated to the soul of man, it will instantly fade away; and the same thing may be said about angels. Strictly speaking, therefore, immortality does not subsist in the nature of souls or of angels, but comes from another source, namely, from the secret inspiration of God, agreeably to that saying, "In him we live, and move, and are." (Acts 17:28.) If any one wish to have a larger and more acute discussion of this subject, let him consult the twelfth book of Augustine "On the City of God." Who inhabiteth unapproachable light He means two things, that God is concealed from us, and yet that the cause of obscurity is not in himself, as if he were hidden in darkness, but in ourselves, who, on account of the weak vision, or rather the dullness of our understanding, cannot approach to his light. We must understand that the light of God is unapproachable, if any one endeavor to approach to it in his own strength; for, if God did not open up the entrance to us by his grace, the prophet would not say: "They who draw near to him are enlightened." (Psalm 34:5.) Yet it is true that, while we are surrounded by this mortal flesh, we never penetrate so far into the deepest secrets of God as to have nothing hidden from us; for "we know in part, and we see as by a mirror, and in a riddle." (1-Corinthians 13:9-12.) By faith, therefore, we enter into the light of God, but only in part. Still it is true, that it is a "light unapproachable" by man. Whom no man hath seen or can see This is added for the sake of additional explanation, that men may learn to look by faith to him, whom they cannot see with the bodily eyes, or even with the powers of their understanding; for I view this as referring not only to the bodily eyes, but also to the faculties of the soul. We must always consider what is the Apostle's design. It is difficult for us to overlook and disregard all those things of which we have immediate vision, that we may endeavor to come to God, who is nowhere to be seen. For this thought always comes into our mind: "How knowest thou if there is a God, seeing that thou only hearest that he is, and dost not see him?" The Apostle fortifies us against this danger, by affirming that it ought not to be judged according to our senses, because it exceeds our capacity; for the reason why we do not see is, that our sight is not so keen as to ascend to so great a height. There is a long dispute in Augustine on this point, because it appears to contradict what is said, in the first Epistle, "Then shall we see him as he is, because we shall be like him." (1 John 3:2.) While he reasons on this subject in many passages, there appears to me to be none in which he explains it more clearly than in the letter which he writes to the widow Paulina. So far as relates to the meaning of the present passage, the answer is easy, that we cannot see God in this nature, as it is said elsewhere, "Flesh and blood shall not possess the kingdom of God." (1-Corinthians 15:50.) We must be renewed, that we may be like God, before it be granted to us to see him. And that our curiosity may not be beyond measure, let us always remember, that the manner of living is of more importance in this inquiry than the manner of speaking. At the same time, let us remember the judicious caution which Augustine gives us, to be on our guard lest, while we are keenly disputing how God can be seen, we lose both peace and sanctification, without which no man can ever see God.

Who only hath immortality - The word here - ἀθανασία athanasia - properly means "exemption from death," and seems to mean that God, in his own nature, enjoys a perfect and certain exemption from death. Creatures have immortality only as they derive it from him, and of course are dependent on him for it. He has it by his very nature, and it is in his case underived, and he cannot be deprived of it. It is one of the essential attributes of his being, that he will always exist, and that death cannot reach him; compare the expression in John 5:26, "The Father hath life in himself," and the notes on that passage.
Dwelling in the light which no man can approach unto - Greek, "Inhabiting inapproachable light." The light where he dwells is so brilliant and dazzling that mortal eyes could not endure it. This is a very common representation of the dwelling place of God. See examples quoted in Pricaeus, in loc. Heaven is constantly represented as a place of the most pure and brilliant light, needing not the light of the sun, or the moon, or the stars Revelation 21:23-24; Revelation 22:5, and God is represented as dwelling in that light, surrounded by amazing and inapproachable glory compare Revelation 4:6; Ezekiel 1:4; Hebrews 1:3.
Whom no man hath seen nor can see - notes on John 1:18.
To whom be honour and power everlasting. Amen - see the notes on Romans 11:36.

Who only hath immortality - All beings that are not eternal must be mutable; but there can be only one eternal Being, that is God; and he only can have immortality.
Dwelling in the light which no man can approach unto - All this is said by the apostle in three words φως οικων απροσιτον, inhabiting unapproachable light. Such is the excessive glory of God, that neither angel nor man can approach it. It is indeed equally unapproachable to all created beings.
Whom no man hath seen, nor can see - Moses himself could only see the symbol of the Divine presence; but the face of God no man could ever see. Because he is infinite and eternal, therefore he is incomprehensible; and if incomprehensible to the mind, consequently invisible to the eye.
To whom - As the author of being, and the dispenser of all good, be ascribed honor and power - the sole authority of all-pervading, all-superintending, all-preserving, and everlasting might.
The words of St. Paul are inimitably sublime. It is a doubt whether human language can be carried much higher, even under the influence of inspiration, in a description of the supreme Being. It is well known that St. Paul had read the Greek poets. He quotes Aratus, Epimenides, and Menander; this is allowed on all hands. But does he not quote, or refer to, Aeschylus and Sophocles too? Scarcely any person suspects this; and yet there is such a complete similarity between the following quotations from the above poets and the apostle's words, that we are almost persuaded he had them in his eye. But if so, he extends the thought infinitely higher, by language incomparably more exalted. I shall introduce and compare with the text the passages I refer to.

Ὁ μονος εχων αθανασιαν, φως οικων απροσιτον.
In the Antigone of Sophocles there is a sublime address to Jove, of which the following is an extract:
Αγηρως χρονῳ Δυναστας,
Κατεχεις Ολυμπου
Μαρμαροεσσαν αιγλαν.
Ver. 608. Edit. Brunk.
"But thou, an ever-during Potentate, dost inhabit the refulgent splendor of Olympus!"
This passage is grand and noble; but how insignificant does it appear when contrasted with the superior sublimity of the inspired writer! The deity of Sophocles dwells in the dazzling splendor of heaven; but the God of Paul inhabits light so dazzling and so resplendent that it is perfectly unapproachable!
Synesius, in his third hymn, has a fine idea on the mode of God's existence, which very probably he borrowed from St. Paul: -
Κεκαλυμμενε νου
Ιδιαις αυγαις.
"O intellectual Being! veiled in thine own effulgence!"
And a few lines after, he says, -
Συ το κρυπτομενον
Ιδιαις αυγαις.
"Thou art He who art concealed by thy splendors."
All these are excellent, but they are stars of the twelfth magnitude before the apostolic Sun.
See a quotation from Euripides, 2-Timothy 4:8.

Who only hath immortality,.... Angels are immortal, and so are the souls of men, and so will be the bodies of men after the resurrection; but then neither of these have immortality of themselves, they have it from God; who only has it, of himself, originally, essentially, and inderivatively.
Dwelling in that light which no man can approach unto; in this present, frail, and mortal state; yea, angels themselves cannot bear the lustre of it, but cover their faces with their wings; for God is light itself, as well as clothes himself with light, as with a garment; and is the Father and fountain of lights to all his creatures.
Whom no man hath seen, nor can see: nowhere but in Christ, at least spiritually and savingly; and that but very imperfectly in the present state: the sin, frailty, and mortality of human nature must be taken away, in order to inherit the kingdom of God, and enjoy the beatific vision of him; which saints in heaven have, who see him as he is, and in such sort as no man now does, or can see him:
to whom be honour and power everlasting, Amen. Which may be considered either as a wish, that such honour, power, and glory might be ascribed unto him, as we supply it; or as an assertion that it is given to him, as it is by the angels, and by the saints in heaven and in earth.

Who only hath immortality--in His own essence, not merely at the will of another, as all other immortal beings [JUSTIN MARTYR, QuÃ&brvbr;st. ad Orthod., 61]. As He hath immortality, so will He give it to us who believe; to be out of Him is death. It is mere heathen philosophy that attributes to the soul indestructibility in itself, which is to be attributed solely to God's gift. As He hath life in Himself, so hath He given to the Son to have life in Himself (John 5:26). The term used in the New Testament for "immortal," which does not occur, is "incorruptible." "Immortality" is found in 1-Corinthians 15:53-54.
dwelling in the light which no man can approach unto--After life comes mention of light, as in John 1:4. That light is unapproachable to creatures, except in so far as they are admitted by Him, and as He goes forth to them [BENGEL]. It is unapproachable on account of its exceeding brightness [THEOPHYLACT]. If one cannot gaze steadfastly at the sun, which is but a small part of creation, by reason of its exceeding heat and power, how much less can mortal man gaze at the inexpressible glory of God [THEOPHYLACT, To Autolycus] (Psalm 104:2; 1-John 1:5).
no man hath seen-- (Exodus 23:20; John 1:18; Colossians 1:15; Hebrews 11:27; 1-John 4:12). Perhaps even in the perfect state no creature shall fully see God. Still the saints shall, in some sense, have the blessedness of seeing Him, which is denied to mere man (Matthew 5:8; 1-Corinthians 13:12; 1-John 3:2; Revelation 22:4).

Who only hath underived, independent immortality. Dwelling in light unapproachable - To the highest angel. Whom no man hath seen, or can see - With bodily eyes. Yet "we shall see him as he is."
