We are told in the Bible to pray continually, but I really liked the way L.B. Cowman addressed this in her devotional book, "Streams in the Desert." As I sit at my desk and type these words, I am the little child she describes--
It is not necessary to be continually speaking to God, or always hearing from God, in order to have a communion or fellowship with Him, for there is an unspeakable fellowship that is sweeter than words. A little child can sit all day long beside his mother, totally engrossed in his playing, while his mother is consumed by her work, and although both are busy and few words are spoken by either, they are in perfect fellowship. The child knows his mother is there, and she knows that his is all right.
In the same way, a believer and his Savior can continue many hours in the silent fellowship of love. And although the believer may be busy with the ordinary things of life, he can be mindful that every detail of life is touched by the character of God's presence, and can have the awareness of His approval and blessing.
