Proverbs 18:10

Here is, 1. God's sufficiency for the saints: His name is a strong tower for them, in which they may take rest when they are weary and take sanctuary when they are pursued, where they may be lifted up above their enemies and fortified against them. There is enough in God, and in the discoveries which he has made of himself to us, to make us easy at all times. The wealth laid up in this tower is enough to enrich them, to be a continual feast and a continuing treasure to them. The strength of this tower is enough to protect them; the name of the Lord is all that whereby he has made himself known as God, and our God, not only his titles and attributes, but his covenant and all the promises of it; these make up a tower, a strong tower, impenetrable, impregnable, for all God's people. 2. The saints' security in God. It is a strong tower to those who know how to make use of it as such. The righteous, by faith and prayer, devotion towards God and dependence on him, run into it, as their city of refuge. Having made sure their interest in God's name, they take the comfort and benefit of it; they go out of themselves, retire from the world, live above, dwell in God and God in them, and so they are safe, they think themselves so, and they shall find themselves so.
