The strength of Puritan character and life lay in prayer and meditation. In this practice the spirit of prayer was regarded as of first importance and the best form of prayer, for living prayer is the characteristic of genuine spirituality. Yet prayer is also vocal and may therefore on occasions be written. Consequently in the Puritan tradition there are many written prayers and meditations which constitute an important corpus of inspiring devotional literature. Too often ex tempore prayer lacks variety, order and definiteness. The reason for this lies partly in a neglect of due preparation. It is here that the care and scriptural thoroughness which others found necessary in their approach to God may be of help. This book has been prepared not to "supply" prayers but to prompt and encourage the Christian as he treads the path on which others have gone before.
