Holy Living and Dying with Prayers

This is a 17th century treatise on how to incorporate prayer into a Christian life.
From the intro: "It is necessary, that every man should consider, that, since God hath given him an excellent nature, wisdom, and choice, an understanding soul, and an immortal spirit, having made him lord over the beasts, and but a little lower than the angels; he hath also appointed for him a work and a service great enough to employ those abilities, and hath also designed him to a state of life after this, to which he can only arrive by that service and obedience. And therefore, as every man is wholly God's own portion by the title of creation, so all our labors and care, all our powers and faculties, must be wholly employed in the service of God, even all the days of our life; that, this life being ended, we may live with him for ever. Neither is it sufficient that we think of the service of God as a work of the least necessity, or of small employment, but that it be done by us as God intended it; that it be done with great earnestness and passion, with much zeal and desire; that we refuse no labor that we bestow upon it much time; that we use the best guides, and arrive at the end of glory by all the ways of grace, of prudence, and religion."
