We read in the Bible that when the Holy Ghost descended on the followers of Christ Jesus on the Day of Pentecost, "every man heard them speak in his own language" (Acts 2:6). Those who had gathered to listen asked one another in amazement, "How hear we every man in our own tongue, wherein we were born?"
Under the marginal heading "Pentecost repeated," Mrs. Eddy writes in Science and Health (p. 43): "The magnitude of Jesus' work, his material disappearance before their eyes and his reappearance, all enabled the disciples to understand what Jesus had said. Heretofore they had only believed; now they understood. The advent of this understanding is what is meant by the descent of the Holy Ghost,—that influx of divine Science which so illuminated the Pentecostal Day and is now repeating its ancient history."
Christian Science explains that the experience of the disciples was not an isolated one, because the Holy Ghost, or Holy Comforter, is always at hand to interpret God to every individual in a way that he can understand. Each one of us has his own pentecostal experience when he discovers for the first time his scientific relationship with God and understands the practical significance of God's love for him. The advent of this understanding comes to him so individually that each one feels as if he were being intimately addressed in his own language and as if the message were intended just for him.
