It is said that Thomas Boston did more to cultivate true Christian devotion in Scotland than any other minister in his generation. And where better to sample his warm spirituality than in his collected writings? Boston's works were first collected and published in 1767 and later reprinted in 1773. The Complete Works, edited by Samuel McMillan and published in twelve volumes in 1853, is now reproduced here with an introduction to Boston's life and theology by Joel R. Beeke and Randall J. Pederson. Boston's writings combine sound exegesis with experiential piety and admonition that continue to encourage a vibrant Reformed spirituality in our own day.
