The day of Pentecost is not the beginning of a denomination. Pentecost celebrated the end of harvest and thanked God for that provision. It had been part of the fabric of Jewish life for generations. This particular Pentecost marked the beginning of a moving of God’s spirit that had never been seen before. It was the fulfillment of a prophecy promised for generations. Those who experienced the first day of Pentecost had been his disciples, heard his teaching, and saw him after the resurrection, but none of that was enough. They all needed the infilling of God’s Holy Spirit to fulfill the fullness of what God promised.
The message of Pentecost is for everyone. God wants an experience with every one of us. They were all together in unity, and God poured His spirit out on them. There were not some more deserving than others; God filled all of them. Pentecost challenges the division that exists in our world. God wants to bless everyone.
The onlookers heard each in the upper room speaking their own language, but they understood. God understands our language and can talk to us in a way we know.
The story of Acts 2 is that if you put yourself in the right place and the correct posture, God will speak to you and provide you with what you need.
