Words from brother Lawrence:*

Whatever we do, even if we are reading the Word or praying, we should stop for a few minutes -- as often as possible -- to praise God from the depths of our hearts, to enjoy Him there in secret. Since you believe that God is always with you, no matter what you may be doing, why shouldn't you stop for awhile to adore Him, to praise Him, to petition Him, to offer Him your heart, and to thank Him?

What could  please God more than for us to leave the cares of the world temporarily in order to worship Him in our spirits? These momentary retreats serve to free us from our selfishness, which can only exist in the world. In short, we cannot show God our loyalty to Him more than by renouncing our worldly selves as much as a thousand times a day to enjoy even a single moment with Him.

This doesn't mean you must leave the duties of the world forever; that would be impossible. Let prudence be your guide. But I do believe that it is a common mistake of spirit-filled persons not to leave the cares of the world from time to time to praise God in their spirits and to rest in the peace of His divine presence for a few moments.

* Brother Lawrence lived over 300 years ago, serving as a cook in a monastery. His meditations and correspondence are collectively known as The Practice of the Presence of God, and are available in several different editions and even on the web.
