Fifty days after the resurrection of Jesus, God began His New Testament Church with an event that has caused controversy ever since. It was on the Day of Pentecost and the disciples were filled with the Holy Spirit and began to speak with other tongues and magnify God. This one event brought the wisdom of God’s Kingdom full circle and has been resisted, scorned, ridiculed, and misunderstood ever since. Due to the controversy, the Church has backed away in fear, using the feeble excuse that it might cause offense. What we must understand is that it was God who did this in public causing His disciples to be accused of being drunk. The Day of Pentecost was the day the earthly ministry of Jesus ended and the earthly ministry of the Holy Spirit began. This book is a verse-by-verse argument in defense of First Corinthians chapter 14. The Apostles were willing to stand for it in Jerusalem and so should we to the uttermost parts of the world.
