Charles H. Spurgeon on Psalms 4:4

"Commune with your own heart upon your bed, and be still." When we are most retired from the world, then we are most fit to have, and usually have, most communion with God. If a man would but abridge himself of sleep, and wake with holy thoughts, when deep sleep falleth upon sorrowful labouring men, he might be entertained with visions from God, though not such visions as Eliphaz and others of the saints have had, yet visions he might have. Every time God communicates himself to the soul, there is a vision of love, or mercy, or power, somewhat of God in his nature, or in his will, is showed unto us. David shows us divine work when we go to rest. The bed is not all for sleep: "Commune with your own heart upon your bed, and be still." Be still or quiet, and then commune with your hearts; and if you will commune with your hearts, God will come and commune with your hearts, too, his Spirit will give you a loving visit and visions of his love.
