Psalms 48:3

Jerusalem is the city of our God: none on earth render him due honour except the citizens of the spiritual Jerusalem. Happy the kingdom, the city, the family, the heart, in which God is great, in which he is all. There God is known. The clearer discoveries are made to us of the Lord and his greatness, the more it is expected that we should abound in his praises. The earth is, by sin, covered with deformity, therefore justly might that spot of ground, which was beautified with holiness, be called the joy of the whole earth; that which the whole earth has reason to rejoice in, that God would thus in very deed dwell with man upon the earth. The kings of the earth were afraid of it. Nothing in nature can more fitly represent the overthrow of heathenism by the Spirit of the gospel, than the wreck of a fleet in a storm. Both are by the mighty power of the Lord.

God is known in her palaces for a refuge. We worship no unknown God. We know him as our refuge in distress, we delight in him as such, and run to him in every time of need. We know nothing else as our refuge. Though we are made kings, and our houses are palaces, yet we have no confidence in ourselves, but trust in the Lord Protector, whose well known power is our bulwark.
