Many of the problems plaguing the church today, such as apathy, conflict, spiritual pride, and spiritual abuse, stem from a poor understanding of who the church is in Christ and God's purpose for her. Whenever we don't understand the purpose of something, we are prone to misuse it. No doubt the newly founded churches in Ephesus and Asia Minor struggled with a lack of understanding as well and, therefore, were plagued with many of the same issues. Paul wrote the letter to the Ephesians to help them grasp God's great plan for the church. He calls many of these insights "mysteries"-truths not fully revealed to past generations, but now fully revealed to us. He describes the church as seated in the heavenly realms in Christ. She is one body-including both Jews and Gentiles. She is God's temple and his masterpiece. She is the bride of Christ and a soldier fighting demonic forces. The more the church grows in her understanding of God's great purpose for her, the more she will live it out and display his glory. Let's study the letter of Ephesians together with The Bible Teacher's Guide. "Expositional, theological, and candidly practical! I highly recommend The Bible Teacher's Guide for anyone seeking to better understand or teach God's Word." -Dr. Young-Gil Kim, Founding President of Handong Global University "Helpful to both the layman and the serious student, The Bible Teacher's Guide, by Dr. Greg Brown, is outstanding!" -Dr. Neal Weaver, President of Louisiana Baptist University
