The Prophet introduced a system of prayer in that it was interwoven into man's daily work: a prayer in the morning when he arose from his bed; a prayer at lunch time, as an indication that if his body needed a diet, so did his spirit; a prayer in the afternoon when he retired from his daily work; a prayer at sunset and a prayer when going to bed.
In the Lord Jesus Christ we see most clearly the union of prayer and life, the harmony and continual interpenetration of the two spheres of life - communion with God and the work on earth.
