The letters of 2 Peter and Jude share several common themes and were designed to strengthen the faith of Christians who were being unsettled by false prophets and teachers within the apostolic churches. Both Peter and Jude show that the problem of false doctrine is nothing new among the people of God. By using examples and warnings from the Old Testament Scriptures they encourage their fellow believers to remain faithful to the gospel, to grow in the grace and knowledge of the Lord Jesus, and to live in the light of Christ's second coming. The Let's Study series is designed to help groups and/or individuals understand and apply the message of Scripture. There is exposition and commentary of the text, and a discussion guide with chapter aims and questions. The material is divided into thirteen sections and provides direction for leading and participating in group study and discussion.
