This great book of fourteen sermons is chock full of encouragement to give our lives to the Great Commission.
Dr. Don Sisk says, "Since pastors need to preach on missions and...missionaries should major on preaching about missions when they are in mission conferences, or doing their deputation or furlough, this book could be a great resource for sermons."
