“He shall dwell on high: his place of defence shall be the munitions of rocks: bread shall be given him; his waters shall be sure.” Isaiah 33:16.
The man to whom God has given grace to be of blameless life dwells in perfect security.
He dwells on high, above the world, out of gunshot of the enemy, and near to heaven. He has high aims and motives, and he finds high comforts and company. He rejoices in the mountains of eternal love, wherein he has his abode.
He is defended by munitions of stupendous rock. The firmest things in the universe are the promises and purposes of the unchanging God, and these are the safeguard of the obedient believer.
He is provided for by this great promise: “Bread shall be given him.” As the enemy cannot climb the fort, nor break down the rampart, so the fortress cannot be captured by siege and famine. The Lord, who rained manna in the wilderness, will keep His people in good store even when they are surrounded by those who would starve them.
But what if water should fail? That cannot be. “His waters shall be sure.” There is a never-failing well within the impregnable fortress. The Lord sees that nothing is wanting. None can touch the citizen of the true Zion. However fierce the enemy, the Lord will preserve His chosen.
Charles H Spurgeon
