Charles H. Spurgeon on Psalms 46:10

Be still and know that I am God. Faith gives the soul a view of the Great God. It teacheth the soul to set his almightiness against sin's magnitude, and his infinitude against sin's multitude; and so quenches the temptation. The reason why the presumptuous sinner fears so little, and the despairing soul so much, is for want of knowing God as great; therefore, to cure them both, the serious consideration of God, under this notion, is propounded: Be still, and know that I am God; as if he had said, Know, O ye wicked, that I am God, who can avenge myself when I please upon you, and cease to provoke me by your sins to your own confusion; and again, know, ye trembling souls, that I am God; and therefore able to pardon the greatest sins, and cease to dishonour me by your unbelieving thoughts of me. William Gurnall.
