Baptist leader Andrew Fuller (1754-1815) deals with the issue of backsliding: when genuine Christians lose their passion for Christ and his kingdom. This was not a theoretical issue for Fuller, therefore, and his words, weighty when he first wrote them, are still worthy of being pondered-and acted upon. Included as an appendix is a poetic application of dealing with such a backslidden heart, written by Samuel Pearce (1766-1799) a close friend and co-labourer for Christ with Fuller. This updated edition is co-published by The Andrew Fuller Center for Baptist Studies at The Southern Baptist Theological Seminary.
