Charles H. Spurgeon on Psalms 84:3

The sparrow hath found an house, etc. The tender care of God, over the least of his creatures, is here most touchingly alluded to. The Psalmist, while an exile, envies them their privileges. He longs to be nestling, as it were, in the dwelling place of God. The believer finds a perfect home and rest in God's altars; or, rather, in the great truths which they represent. Still, his confidence in God is sweetened and strengthened by the knowledge of his minute, universal, providential care. It becomes his admiring delight. "God fails not, "as one has beautifully said, "to find a house for the most worthless, and a nest for the most restless of birds." What confidence this should give us! How we should rest! What repose the soul finds that casts itself on the watchful, tender care of him who provides so fully for the need of all his creatures! We know what the expression of "nest" conveys, just as well as that of "a house." Is it not a place of security, a shelter from storm, a covert to hide oneself in, from every evil, a protection from all that can harm, "a place to rest in, to nestle in, to joy in?" But there is one thing in these highly privileged birds which strike us forcibly in our meditations —they knew not him from whom all this kindness flowed —they knew neither his heart nor his hand. They enjoyed the rich provisions of his tender care; he thought of everything for their need, but there was no fellowship between them and the Great Giver. From this, O my soul, thou mayest learn a useful lesson. Never rest satisfied with merely frequenting such places, or with having certain privileges there; but rise, in spirit, and seek and find and enjoy direct communion with the living God, through Jesus Christ our Lord. The heart of David turns to God himself. My heart and my flesh crieth out for the living God. Things New and Old.
