I am amazed and fascinated by the variety of calls that each person experiences and makes during his or her lifetime. We are all bombarded by calls, yet I realize that we cannot exist without them. This book’s chronology of the variety of calls speaks to one specific call—the call to salvation. Many from different lifestyles, social status, and points of view responded to this call and experienced a rewarding and complete life in service to God. The path to this enriched life was not easy for the many that chose to accept the call. Persecution, imprisonment, beatings, and other atrocities are documented and outlined between the covers of this book. Yet irrespective of the obstacles, perseverance and victory won the day. From a biblical perspective, God began the call in the book of Genesis. Through his divine foreknowledge, he knew what man’s response would be, yet he still made the call. The accounts of the many trailblazers described in this book have left their footprints in the sands of time as a testimony that decisions made have eternal consequences. The author hopes that close examination of the lives lived will be a source of encouragement to respond positively to the call.
