We are prone to think, for example, that converse with Christian brethren, and the general round of Christian activity, especially when we are much busied with preaching the Word and visits to inquiring or needy souls, make up for the loss of aloneness with God in the secret place. We hurry to a public service with but a few minutes of private prayer, allowing precious time to be absorbed in social pleasures, restrained from withdrawing from others by a false delicacy, when to excuse ourselves for needful communion with God and his word would have been perhaps the best witness possible to those whose company was holding us unduly! How often we rush from one public engagement to another without any proper interval for renewing our strength in waiting on the Lord, as though God cared more for the quantity than the quality of our service!

Here Mr. Müller had the grace to detect one of the foremost perils of a busy man in this day of insane hurry. He saw that if we are to feed others we must be fed; and that even public and united exercises of praise and prayer can never supply that food which is dealt out to the believer only in the closet– the shut-in place with its closed door and open window, where he meets God alone.
