Before nine o'clock in the morning, ten days after the Saviors' ascension, and fifty days after the Passover associated with the crucifixion, the apostles held a memorable meeting. As they sat "with one acord in one place" "suddenly there came a sound from heaven as of a rushing mighty wind, and it filled all the house where they were sitting." Thus came the baptism by fire and the Holy Ghost as Christ had promised. The Comforter about which their Master had so often spoken had at length come to them, to guide and to inspire them as Jesus had done in person. [Sidenote: The Gift of Tongues.] Immediately a wonderful manifestation took place. Though nearly all the apostles were Galileans and spoke the same language, yet when they began to bear testimony of Christ and His Gospel, they "began to speak with other tongues as the spirit gave them utterance." That a remarkable thing had occurred was soon noised about the city, and people in great numbers gathered around the apostles. In the crowd were Jews from many nations who had come to Jerusalem to celebrate Pentecost. These spoke the language of the country from which they came. Imagine their amazement when every one heard the Gospel preached in his own tongue! "Are not theses men who speak Galileans?" they asked. "Yes," was the answer. "Then how hear we every man in his own tongue, wherein we were born?" As the apostles, one after another, told of the salvation of man through the Gospel of Jesus Christ, some of the people were amazed, and some amused, but all were perplexed. "What does this mean?" asked some. "They act as though they are drunken," said others. Then Peter arose, and, in mighty power, addressed the multitude. "Ye men of Judea," he began, "and all ye that dwell at Jerusalem; be this known unto you, and hearken to my words: [Sidenote: Peter's Address.] "For these are not drunken as ye suppose, seeing it is but the third hour of the day. "But this is what was spoken by the Prophet Joel." [1] Undoubtedly only a small part of Peter's address is given to us; but as we read his inspired words, and partake of the fearlessness with which he told the Jews that they had crucified the Christ, we readily become convinced that the weakness he manifested about a month and a half before, has been replaced by the strength of the man of God. Then he stammered and swore, "I know not the man;" _now_, he declared, "This Jesus hath God raised up, whereof, we are all witnesses." [Sidenote: His Fearlessness.] With all the courage of his convictions, and with the power of the Holy Ghost, he added: "Therefore, let all the house of Israel know assuredly, God hath made that same Jesus, whom ye have crucified, both Lord and Christ." As they heard of the wickedness in crucifying the Christ and of many other sins, they desired to get forgiveness for what they had done, and cried out to Peter--and the other apostles, "Men and brethren, what shall we do?"
