And I will ask the Father, and he will give you another Advocate, who will never leave you. He is the Holy Spirit, who leads into all truth. The world cannot receive him, because it isn’t looking for him and doesn’t recognize him. But you know him, because he lives with you now and later will be in you. [John 14:16-18 (NLT)]
After His resurrection, Jesus spent forty days with his disciples. On the fortieth day, He told them to remain in Jerusalem until they received the promised gift of the Holy Spirit. Then, with his followers watching, Jesus was taken up in a cloud and ascended into heaven. Bewildered, the disciples stood there until two angels promised that someday Jesus would return. We know the disciples attended to business by choosing a replacement for Judas, but how else did they spend their time? There were twelve apostles and about 120 believers. How difficult was it for this diverse group of people to keep the faith and wait ten days for something which seemed so perplexing? Where was this Holy Spirit promised to them? When would Jesus return? Did they grow impatient or begin to doubt what they’d seen with their eyes?
Yesterday was Pentecost (meaning fiftieth). At that first Pentecost, all of Jesus’ followers were gathered together because the Jewish holiday of Shavu’ot was being observed. Also called the Feast of Weeks, Shavu’ot (or Pentecost) occurred seven weeks after Passover and celebrated both the first harvest and Moses being given the law at Mt. Sinai. It was one of three pilgrimage festivals when all able-bodied Jewish men were required to visit the temple and offer sacrifices.
It was on this fiftieth day after Jesus’ resurrection that the Holy Spirit, accompanied by high winds and tongues of fire, descended upon Christ’s followers. As every believer was filled with the Spirit’s power, he or she began to speak in other languages. Shavu’ot had brought together Jews from fifteen or more different regions, each with its own language, and yet everyone was able to understand the Spirit-filled Christians as they spoke. The Holy Spirit had empowered the disciples to bring Christ’s message of salvation to all people.
It hardly seems an accident that God chose Shavu’ot for such a miraculous event to occur and not just because Jerusalem was teeming with people from far and wide. On a day when people went to the temple to be in God’s presence, the Holy Spirit’s arrival meant that God could always be present in His people. On a day that commemorated the giving of the law at Mt. Sinai—an external means of keeping Israel from sin—the Holy Spirit descended and believers no longer had to adhere to laws carved on stone. By His power, the law was now written on their hearts and, through Him, believers could live righteously. On a day that celebrated the first harvest, 3,000 people were baptized. That incredible first harvest of souls marked the beginning of the New Testament church. So, in a way, while Christmas celebrates the birth of Jesus, Pentecost celebrates the birth of the Christian church.
