Acts 2

1 "Pentecost" means "fiftieth day" in Greek. It referred to the Feast of Weeks described in Lev 23:15-22. This feast was also called the Feast of Ingathering (Ex 23:16) and the Day of the First Fruits (Num 23:26). Pentecost was celebrated on the seventh Sunday after the first grain of the barley harvest was "waved" before God on the Saturday during the Passover week. It marked the end of the barley harvest and the beginning of the wheat harvest.

The disciples continued to meet and pray in Jerusalem. On this day, they were all together. There were no divisions among them. They agreed in prayer and obedience to what Jesus had commanded.

2 The disciples heard a sound like rushing wind. This does not mean that the Holy Spirit is the wind, but the wind symbolizes the Spirit because of its power and invisibility. The Greek word for "spirit," Pneuma, is also used for "wind."
3 The Spirit then appeared as some kind of light source. The light divided and the resulting lights hovered over the heads of each person. The lights appeared like little flames, or "tongues," of fire.
4 The Holy Spirit did not remain external. He began to indwell believers at that moment. This is considered the beginning of the Christian Church.

The first task of the Spirit was to allow the disciples to speak in other languages. Jerusalem was filled with Jews from all over the world, and the disciples were to preach the Good News of Jesus to them with the assistance of the Holy Spirit.

44 The first Christians were noted for their willingness to share with one another -- so much so that they did not consider themselves to have anything be their "own."
45 Some things would have been difficult to share. For instance, a high-value piece of artwork would have little value to those who were in need. Instead of keeping these possessions they sold them and used the money to help the poor among them.
46 The Temple served as a "church" for the first Christians in Jerusalem. However, they did not confine their faith to a building. Instead, they went from house to house to build each other up on a daily basis. Christianity is more than a once-a-week activity. It is a complete change of worldview that affects the Christian every day of the week. Some may feel they are too busy for daily fellowship, but it is highly beneficial to be reminded frequently throughout the week what God has done for us and how He works in our lives each day.

House meetings can be more informal and inviting to those who are uncomfortable in church. Those who do not yet believe will feel more comfortable in a home environment where he can get to know his Christian neighbors firsthand. Once he knows people and is interested in knowing Christ, a more formal church service will be less intimidating -- especially if he can go with a friend, instead of walking into a room of strangers. Thus, a church body should encourage individuals to reach out to their neighbors and get to know them on a personal basis. When they see the reality of Christ in their friends and neighbors, they are more likely to believe that Jesus can work in their lives as well.

47 These fellowship meetings were centered on God as is evidenced by their remembrance of the Lord's Supper and their continual praise of God.

As Christians live the way God desires us to, we are likely to gain the respect of those around us, including non-Christians. When we are honest and loving to others, people take note. When people see that it is possible to have God in their hearts and be able to live with hope and joy, they will be attracted. There will be those who persecute Christians, but there are others who will be convinced that life with God is real when they see it in the lives of Christians.
