Summary: The purpose of the Church as expressed in Acts 2:42
INTRO.: Many are not aware the Day of Pentecost is the birthday of the Church. On the first Pentecost after the resurrection of Jesus, the Holy Spirit fell on the Apostles of Jesus in fulfillment of Jesus’ promise. Through the Holy Spirit, the Apostles were empowered to preach the Gospel flawlessly in many languages.
On that same day, the very first Gospel sermon offering salvation through the death and resurrection of Jesus was preached. The Church began when the Gospel invitation of verse 38 was offered and 3000 accepted the invitation and became the nucleus of the New Testament Church.
This was an auspicious start. But, there was an immediate need to determine what could be done with 3000 new converts. Under the direction of the Spirit, the Apostles led the new congregation in doing the things necessary to ensure survival and to meet certain necessary goals.
Their goals were threefold: to establish a community that would endure, to spread the Gospel message in fulfillment of Jesus’ commission, and to help believers mature in faith.
They must have done something right. We are here today after 2000 years. However, sometimes it is necessary to remind ourselves WHY we are here. Many in our day have lost sight of the nature and purpose of the Church.
To get a better idea of what we should be doing, let’s go back to the birthday of the Church and see what they did, to what did they devote themselves. Let’s see what the early Church offered its people and the world. Acts 2:42 (quickview)  tells the story.
I. Early Christians devoted themselves to the Word of God:
A. This is how the work was begun
1. 12 men were carefully chosen and trained by Jesus to teach His Word.
2. He commissioned them to carry His message. Matt. 28:19, 20
B. On Pentecost, their work began. Their work was teaching.
2. 3000 were convinced of Jesus’ claims and baptized for forgiveness of sin. The Church had begun.
3. The Apostles continued to teach in obedience to Jesus’ commission.
C. The Apostles’ teaching is important.
1. They were entrusted to teach God’s will for men.
2. Their teaching frees men from sin. Rom. 6:17, 18
3. The Church carries on this work by teaching the Bible, which is the recorded words of Jesus’ Apostles, along with prophets and others through whom God has revealed Himself.
4. The Church offers opportunities to learn God’s will for your life.
A. They became part of a fellowship:
1. That is, they all became "fellow Christians."
2. They became concerned for one another. They shared food &possessions & prayed for one another.
3. They saw themselves as spiritual brothers and sisters, part of the family of God.
B. When we become part of the Church we become part of something very important.
