Verse 11. - For the Lord God is a Sun and Shield; i.e. not only a "Shield" or protection, as he has been already called (ver. 9), but also a "Sun," the source of life and light, of joy and happiness (comp. Isaiah 60:19, 20; Malachi 4:2). The Lord will give grace and glory. Inward grace, outward splendour and glory (Revelation 21:11-24). No good thing will he withhold from them that walk uprightly (see 1 Corinthians 2:9; 1 Timothy 4:8; and Psalm 34:10).

84:8-12 In all our addresses to God, we must desire that he would look on Christ, his Anointed One, and accept us for his sake: we must look to Him with faith, and then God will with favour look upon the face of the Anointed: we, without him, dare not show our faces. The psalmist pleads love to God's ordinances. Let us account one day in God's courts better than a thousand spent elsewhere; and deem the meanest place in his service preferable to the highest earthly preferment. We are here in darkness, but if God be our God, he will be to us a Sun, to enlighten and enliven us, to guide and direct us. We are here in danger, but he will be to us a Shield, to secure us from the fiery darts that fly thick about us. Through he has not promised to give riches and dignities, he has promised to give grace and glory to all that seek them in his appointed way. And what is grace, but heaven begun below, in the knowledge, love, and service of God? What is glory, but the completion of this happiness, in being made like to him, and in fully enjoying him for ever? Let it be our care to walk uprightly, and then let us trust God to give us every thing that is good for us. If we cannot go to the house of the Lord, we may go by faith to the Lord of the house; in him we shall be happy, and may be easy. That man is really happy, whatever his outward circumstances may be, who trusts in the Lord of hosts, the God of Jacob.For the Lord God is a sun and shield,.... Christ is "the sun of righteousness", and it is in the house of God that he arises upon his people with healing in his wings, Malachi 4:2 he is like the sun, the great light, the fountain of light, the light of the world, that dispels darkness, makes day, and gives light to all the celestial bodies, moon and stars, church and ministers; he is a "sun" to enlighten his people with the light of grace, to warm them with the beams of his love, to cheer and refresh their souls with the light of his countenance, and to make them fruitful and flourishing and he is a "shield" to protect them from all their enemies; he is the shield of faith, or which faith makes use of, against the temptations of Satan; he is the shield of salvation, and his salvation is a shield which shelters from divine justice, and secures from wrath to come:

the Lord will give grace and glory: he gives converting grace, the first grace, and all future supplies of it; he gives sanctifying grace, all sorts of it, faith, hope, love, and every other; he gives justifying, pardoning, adopting, and persevering grace, and all freely; he gives honour and glory among men, fellow creatures, and fellow Christians; and he gives eternal glory, the glory his Father gave him, the crown of glory, life, and righteousness: this is the gift of God through Christ; Christ gives a right unto it, meetness for it, and the thing itself; and in his house and ordinances, as he gives more grace to the humble that wait upon him, so he encourages and increases their hope of glory; and he that gives the one will certainly give the other; for these two are inseparably connected together, so that he that has the one shall enjoy the other:

no good thing will he withhold from them that walk uprightly; that walk by faith, and on in Christ, as they have received him; who have their conversation according to the Gospel of Christ, and walk in the uprightness and sincerity of their hearts; from such the Lord will not withhold any good thing he has purposed for them, promised to them, or laid up for them in covenant; no spiritual good thing appertaining to life and godliness, and no temporal blessing that is good for them; he will deny them no good thing they ask of him, not anything that is good for them; and he will not draw back any good things he has bestowed on them, his gifts are without repentance.
