I'm not sure if anyone here has mentioned the book, "One Thing You Can't Do In Heaven" by Mark Cahill, but I read it some time ago, and God really used it in my life. It's a very practical book that reminds you that you can only share your faith here on Earth, and encourages you to do so. One of the chapters was on using tracts in evangelism, and he had a quote by Spurgeon that I had never heard before. Spurgeon said, "When preaching and private talk are not available, you need to have a tract ready....Get good striking tracts, or none at all. But a touching gospel tract may be the seed of eternal life. herefore, do not go out without your tracts." I was so encouraged to know that C. H. Spurgeon himself, the prince of preachers, used gospel tracts regularly. One last thing, you can actually listen to the audio version of the book free on his website (www.markcahill.org).
