Dr. Thompson recounts the undeniable call of God on his life with moving stories both of his personal faith story and in a middle of nowhere village "hospital" in Gabon. He does so with humor, humility, and honesty. Following Jesus is costly, and Thompson is an example to all Christians to use the talents he has given them for the glory of Christ. This left me in tears on several occasions. "If you love me, you will obey my commands," said Jesus. We are all on call.
