If you have more confusion than clarity concerning the Holy Spirit, you’re not alone. Some groups have treated the Spirit as a license for casting off scriptural authority. Others have reacted by minimizing His role. The result is that teaching about the third person of the Trinity often leaves much to be desired. But Jesus did not intend for His followers to linger in confusion; rather, he wanted them to realize the Spirit’s power in their lives. We hope that this course will begin to clarify the Holy Spirit for you: what Jesus taught the disciples about it, how the early Christians thought about it, and how the Holy Spirit is alive today.
