Hmmm! Who's Speaking? is an inspiring collection of first-hand reports, so to speak, that the author gathered by visiting a variety of churches from a wide array of religious denominations and backgrounds. Then he shared them first with his minister and then others so that each may learn something from other members of the body of Christ. Some of his visits were to mosques, temples, synagogues, and even cults. The author hopes his reports of visits to denominational and nondenominational churches will encourage some readers who do not attend a church, or maybe feel uncomfortable where they do go, to check out another church. He feels God has a specific church in mind for you so that you will become involved in spreading the Good News about the Father, Son, and Holy Spirit. And some of his stories in this book are about other happenings where God got his message over to the author through experiences as a Boy Scout chaplain, a Billy Graham Emergency Response chaplain, and as a chaplain for the Tulsa Juvenile Detention Center. Then there are stories about ways and things God used to get his attention either physically or with words or music or even animals like foxes, donkeys, frogs, birds, and even insects. The author's hope is that you, too, may recognize something similar that's happened in your life, and maybe you'll think, Hmmm! Was that the Father, Son and Holy Spirit speaking?
