Heir to a Spiritual Treasure. In this chapter-by-chapter study of the Second Epistle to Timothy, Guy King invites us to look over Timothys shoulder as we study this prison message from his spiritual father, the Apostle Paul.This letter is a true legacy of a spiritual treasure passed from father to son which time does not tarnish. And now the treasure passes on to you. A great book for small groups or Bible study leaders.
