"One cause, therefore, of the dulness of many Christians in prayer, is their slight acquaintance with the sacred volume. They hear it periodically, they read it occasionally, they are contented to know it historically, to consider it superficially; but they do not endeavour to get their minds imbued with its spirit. If they store their memory with its facts, they do not impress their hearts with its truths. They do not regard it as the nutriment on which their spiritual life and growth depend. They do not pray over it; they do not consider all its doctrines as of practical application; they do not cultivate that spiritual discernment which alone can enable them judiciously to appropriate its promises, and apply its denunciations to their own actual case. They do not use it as an unerring line, to ascertain their own rectitude, or detect their own obliquities." * * * * * "The discrepancies between our prayers and our practice do not end here. How frequently are we solemnly imploring of God that 'His kingdom may come,' while we are doing nothing to promote His kingdom of grace here, and consequently His kingdom of glory hereafter." * * * * * "Prayer draws all the Christian graces into its focus. It draws Charity, followed by her lovely train, her forbearance with faults, her forgiveness of injuries, her pity for errors, her compassion for want. It draws Repentance, with her holy sorrows, her pious resolutions, her self-distrust. It attracts Faith, with her elevated eye,--Hope, with her grasped anchor,--Beneficence, with her open hand,--Zeal, looking far and wide to serve,--Humility, with introverted eye, looking at home. Prayer, by quickening these graces in the heart warms them into life, fits them for service, and dismisses each to it appropriate practice. Cordial prayer is mental virtue; Christian virtue is spiritual action."--_The Spirit of Prayer_ (chapters iii., viii., and xi.).
