Ortberg ("The Me I Want To Be"; "Soul Keeping"), a senior pastor at Menlo Park Presbyterian Church in California, has written a new book that offers hope and guidance to embrace change and the unknown. The titles of his previous works are indicative of his approach: catchy, contemporary, in touch with Lewis Carroll and "Sesame Street" as well as modern counseling modes, yet grounded in narratives from the Old and New Testaments. His principal interest is spiritual formation, which is in some ways an ideal match for Americans today. It is less concerned with dogmatics than with the development of the self. Ortberg is adept in using his pastoral experience and knowledge of scripture to develop his argument, which stresses faith in God's invitations to Christians to move forward, into the unknown. VERDICT A mainstream Christian's approach to trusting God and improving the self; solid for church groups, pastors, and individual Christians.--Library Journal
