The Great Work of Prayer

The work of redemption, in all the various forms in which it is carried on, is truly and emphatically God's work. But it is worthy of grateful notice, that our heavenly Father, in doing his own work, condescends to accept of human agency. Placing the Infinite in alliance with the finite, he allows man to be a co-worker with himself. And one of man's great works, that work without which nothing else is available, is prayer.

But, in saying this, it should be added, that we use the term prayer, not in the restricted sense of particular or specific supplication, but in the more general sense in which it is sometimes employed, namely, as expressive of communion with God in all its forms.
