Now, beloved, when you are worshipping God, shout if you are filled with holy gladness. If the shout comes from your heart, I would not ask you to restrain it. God forbid that we should judge any man’s worship! But do not be so foolish as to suppose that because there is loud noise there must also be faith. Faith is a still water, it flows deep. True faith in God may express itself with leaping and with shouting; and it is a happy thing when it does: but it can also sit still before the Lord, and that perhaps is a happier thing still. (Spurgeon)
