Samuel Lee (1625-1691) was a learned puritan divine and preacher who ministered in both England and New England.What is prayer? And what is the difference between prayer and secret prayer? What is the best method for secret prayer according to Scripture for the Christian? Lee expounds Matthew 6:6 in a most able and helpful manner to show the Christian what God expects in secret prayer, But thou, when thou prayest, enter into thy closet, and when thou hast shut thy door, pray to thy Father which is in secret; and thy Father which seeth in secret shall reward thee openly. Lee covers the duty of secret prayer, managing secret prayer, various important directions for secret prayer, how one knows when their prayers are answered, how to discern if one has prayed well in order to gain the most profit from secret prayer, a number of questions on prayer both generally and specifically, and a final application of how prayer can be made most rewarding to the Christian overall.
