People tend to avoid what they can’t control. Believers often shy away from the Holy Spirit because we don’t know who He really is or what He might do. But if we will let Him into our lives, He will come with His power and change us forever. In School of the Spirit, Pastor Lee Cummings encourages believers to get to know the Holy Spirit, the most misunderstood Person of the Trinity. He illuminates biblical truths in a clear, easy-to-understand way and answers many common questions.
