Evangelism: Genesis to the Ascension is an evangelistic, chronological, Bible teaching program which traces God's redemptive plan through the Old Testament and the Gospels. This resource will help teachers set the stage for the good news of Christ by first laying a solid foundation from the Old Testament of who God is and how he has interacted with people throughout history. The Building on Firm Foundations (BOFF) series is an extensive teaching program which helps equip leaders and disciple-makers to teach God's Word. Developed especially with cross-cultural evangelism in a church planting context in mind, the Building on Firm Foundations lessons have been used in over 250 people groups with exceptional results.
