(1) The Lord is my light.--This noble thought appears nowhere else so grandly, though we may compare Isaiah 60:1. The Latin of the Vulgate, "Dominus illuminatio mea," is the motto of the University of Oxford, and expands in a new but true direction the thought of the ancient bard. To him, Jehovah was the guiding and cheering beacon-fire, proclaiming his victory and pointing him the happy homeward way. From this to the belief in God as the source both of moral and intellectual light, is a long but glorious stage, along which the world has been guided by such words as Isaiah 60:1, still more by the recognition of the incarnate Son as the Light of men (John 1:5; John 3:19; John 12:46, &c).

Strength.--Better, defence or bulwark; Heb., maoz, rendered "rock," Judges 6:26 (margin, strong place); used in Isaiah 17:9 of fortified cities; as here, Psalm 37:39; Psalm 43:2; LXX., "shields;" Vulg., "protector."

Verse 1. - The Lord is my Light (comp. John 1:7-9; John 12:35, 36, 46; 1 John 1:5). The statement does not occur in any other place in the Old Testament, though the idea may be found in Isaiah 60:1, 20; Micah 7:8; and elsewhere. Light has been well called "this profoundly beautiful name of God" (Delitzsch). And my Salvation (comp. Psalm 18:2; Psalm 62:2, 6). Whom shall I fear? "If God be for us, who can be against us?" (Romans 8:31). Who can be to be feared? (see Psalm 118:6). Not man certainly; for" what can man do unto us?" Not other gods; for they are nonentities. Not devils; for they can do nothing but by God's permission. The Lord is the Strength of my life; literally, the stronghold (comp. Psalm 28:8; Psalm 31:4; Psalm 71:2; Psalm 144:2). Of whom shall I be afraid? The question is superfluous, but is repeated to complete the balance of the clauses.

27:1-6 The Lord, who is the believer's light, is the strength of his life; not only by whom, but in whom he lives and moves. In God let us strengthen ourselves. The gracious presence of God, his power, his promise, his readiness to hear prayer, the witness of his Spirit in the hearts of his people; these are the secret of his tabernacle, and in these the saints find cause for that holy security and peace of mind in which they dwell at ease. The psalmist prays for constant communion with God in holy ordinances. All God's children desire to dwell in their Father's house. Not to sojourn there as a wayfaring man, to tarry but for a night; or to dwell there for a time only, as the servant that abides not in the house for ever; but to dwell there all the days of their life, as children with a father. Do we hope that the praising of God will be the blessedness of our eternity? Surely then we ought to make it the business of our time. This he had at heart more than any thing. Whatever the Christian is as to this life, he considers the favour and service of God as the one thing needful. This he desires, prays for and seeks after, and in it he rejoices.The Lord is my light and my salvation; whom shall I fear?.... The Targum in the king of Spain's Bible explains it, "the Word of the Lord is my light"; and so Ainsworth cites it; that is, Christ the eternal Word, in whom "was life, and that life was the light of men", John 1:4; and the psalmist is not to be understood of the light of nature and reason, with which the Logos, or Word, enlightens every man that comes into the world; nor merely in a temporal sense, of giving him the light of prosperity, and delivering him from the darkness of adversity; but of the light of grace communicated to him by him who is the sun of righteousness, and the light of the world; and by whom such who are darkness itself, while in an unregenerate state, are made light, and see light; all the light which is given to men at first conversion is from Christ; and all the after communications and increase of it are from him; as well as all that spiritual joy, peace, and comfort they partake of, which light sometimes signifies, Psalm 97:11; and which the psalmist now had an experience of; enjoying the light of God's countenance, and having discoveries of his love, which made him fearless of danger and enemies: and such who are made light in the Lord have no reason to be afraid of the prince of darkness; nor of the rulers of the darkness of this world; nor of all the darkness, distress, and persecutions they are the authors of; nor of the blackness of darkness reserved for ungodly men; for their light is an everlasting one, and they are made meet to be partakers of the inheritance with the saints in light: and the more light they have, the less fear; and what made the psalmist still more fearless was, that Christ was his "salvation"; by the light which the Lord was to him, he saw his need of salvation, he knew that his own righteousness would not save him; he was made acquainted with the design and appointment of the Lord, that Christ should be salvation to the ends of the earth; he had knowledge of the covenant of grace, and faith in it, which was all his salvation, 2 Samuel 23:5. Salvation was revealed to the Old Testament saints, in the promises, sacrifices, types, and figures of that dispensation; and they looked through them to him for it, and were saved by him, as New Testament believers are; and they had faith of interest in Christ, and knew him to be their Saviour and Redeemer, as did Job, and here the psalmist David: and such who know Christ to be their salvation need not be afraid of any person or thing; not of sin, for though they fear, and should fear to commit it, they need not fear the damning power of it, for they are saved from it; nor of Satan, out of whose hands they are ransomed; nor of the world, which is overcome by Christ; nor of the last enemy, death, which is abolished by him; nor of hell, and wrath to come, for he has delivered them from it;

the Lord is the strength of my life; of whom shall I be afraid? meaning not of his natural life, though he was the God of his life, who had given it to him, and had preserved it, and upheld his soul in it; but of his spiritual life: Christ is the author of spiritual life, he implants the principle of it in the hearts of his people, yea, he himself is that life; he lives in them, and is the support of their life; he is the tree of life, and the bread of life, by which it is maintained; and he is the security of it, it is bound up in the bundle of life with him, it is hid with Christ in God; and because he lives they live also; and he gives unto them eternal life, so that they have no reason to be afraid that they shall come short of heaven and happiness; nor need they fear them that kill the body and can do no more; nor any enemy whatever, who cannot reach their spiritual life, nor hurt that, nor hinder them of the enjoyment of eternal life.
