Lighthouse Series Booklet. When Jesus walked the earth, He performed miracles. The early Christians also performed miracles and spoke in tongues. Some believers claim that these events still happen, and are manifestations of Holy Spirit power. Others label them as demonic deceptions. Who is right? Miracles, Signs, and Wonders guides us to Scripture to see what Christ and the apostles taught and lived regarding this doctrine. Knowing the truth will guard us from false doctrine and inspire in us an active faith that takes God at His Word.
