Charles H. Spurgeon on Psalms 46:5

God is in the midst of her, etc. The enemies of the church may toss her as waves, but they shall not split her as rocks. She may be dipped in water as a feather, but shall not sink therein as lead. He that is a well of water within her to keep her from fainting, will also prove a wall of fire about her to preserve her from falling. Tried she may be, but destroyed she cannot be. Her foundation is the Rock of Ages, and her defence the everlasting Arms. It is only such fabrics as are bottomed upon the sand, that are overthrown by the wind. The adversaries of God's people will push at them as far as their horns will go, but when they have scoured them by persecution, as tarnished vessels, then God will throw such wisps into the fire. William Secker.
