Charles H. Spurgeon on Psalms 87:1

His foundation is in the holy mountains. The Psalm begins abruptly, the poet's heart was full, and it gained vent on a sudden.

"God's foundation stands forever

On the holy mountain towers;

Sion's gates Jehovah favours

More than Jacob's thousand bowers."

Sudden passion is evil, but bursts of holy joy are most precious. God has chosen to found his earthly temple upon the mountains; he might have selected other spots, but it was his pleasure to have his chosen abode upon Zion. His election made the mountains holy, they were by his determination ordained and set apart for the Lord's use. The foundation of the church, which is the mystical Jerusalem, is laid in the eternal, immutable, and invincible decrees of Jehovah. He wills that the church shall be, he settles all arrangements for her calling, salvation, maintenance and perfection, and all his attributes, like the mountains round about Jerusalem, lend their strength for her support. Not on the sand of carnal policy, nor in the morass of human kingdoms, has the Lord founded his church, but on his own power and godhead, which are pledged for the establishment of his beloved church, which is to him the chief of all his works. What a theme for meditation is the founding of the church of God in the ancient covenant engagements of eternity; the abrupt character of this first verse indicates long consideration on the part of the writer, leading up to his bursting forth in wonder and adoration. Well might such a theme cause his heart to glow. Rome stands on her seven hills and has never lacked a poet's tongue to sing her glories, but more glorious far art thou, O Zion, among the eternal mountains of God: while pen can write or mouth can speak, thy praises shall never lie buried in inglorious silence.
