Charles H. Spurgeon on Psalms 84:4

Blessed are they that dwell in thy house. Those he esteems to be highly favoured who are constantly engaged in divine worship —the canons residentiary, yea, the pew openers, the menials who sweep and dust. To come and go is refreshing, but to abide in the place of prayer must be heaven below. To be the guests of God, enjoying the hospitalities of heaven, set apart for holy work, screened from a noisy world, and familiar with sacred things —why this is surely the choicest heritage a son of man can possess. They will be still praising thee. So near to God, their very life must be adoration. Surely their hearts and tongues never cease from magnifying the Lord. We fear David here drew rather a picture of what should be than of what is; for those occupied daily with the offices needful for public worship are not always among the most devout; on the contrary, "the nearer the church the further from God." Yet in a spiritual sense this is most true, for those children of God who in spirit abide even in his house, are also ever full of the praises of God. Communion is the mother of adoration. They fail to praise the Lord who wander far from him, but those who dwell in him are always magnifying him.

"Selah." In such an occupation as this we might be content to remain for ever. It is worth while to pause and meditate upon the prospect of dwelling with God and praising him throughout eternity.
