This guide to prayer covers the types of prayer, length of prayer, the voice in public prayer, body posture, how to improve praying, the Holy Spirit in prayer and exhortations to pray. Isaac Watts is quite honest in his calling out wrong activities that might be involved in prayer. As he says, "The form, method, and expression, together with other attendants of it, such as voice and gesture, have been so little treated of, that few Christians have any clear or distinct knowledge of them: and yet all these have too powerful an influence upon the soul in its most spiritual exercises."
