Charles H. Spurgeon on Psalms 114:2

Judah was his sanctuary, and Israel his dominion. These people were God's sanctification and dominion, that is, witnesses of his holy majesty in adopting them, and of his mighty power in delivering them: or, his sanctification, as having his holy priests to govern them in the points of piety; and dominion, as having godly magistrates ordained from above to rule them in matters of policy: or, his sanctuary, both actually, because sanctifying him; and passively, because sanctified of him...This one verse expounds and exemplifies two prime petitions of the Lord's Prayer. "Hallowed be thy name, thy kingdom come": for Judah was God's sanctuary, because hallowing his name;and Israel his dominion, as desiring his kingdom to come. Let every man examine himself by this pattern, whether he be truly the servant of Jesus his Saviour, or the vassal of Satan the destroyer. If any man submit himself willingly to the domineering of the devil, and suffer sin to reign in his mortal members, obeying the lusts thereof, and working all uncleanness even with greediness; assuredly that man is yet a chapel of Satan, and a slave to sin. On the contrary, whosoever unfeignedly desires that God's kingdom may come, being ever ready to be ruled according to his holy word, acknowledging it a lantern to his feet, and a guide to his paths; admitting obediently his laws, and submitting himself alway to the same; what is he, but a citizen of heaven, a subject of God, a saint, a sanctuary? —John Boys.
