In the book of Acts, Luke continues the story he began in his Gospel. The book starts off with the apostles (those who saw Jesus) being told by Jesus to wait. The apostles had walked with Jesus through Jesus’ ministry, they witnessed His death and they had just witnessed Him being raised from the dead. We can imagine that they were ready to go out and tell the world what they have experienced. However, Jesus said to wait. The reason being is that He didn’t want them going at it alone. He promised to give them the Holy Spirit. This would be how the early church had the power to get the gospel (good news) to the ends of the earth.
Just one chapter later, what Jesus promised has happened. The Holy Spirit comes! In VS 4 we see the word “enabled”. This means that the Holy Spirit gave them the power to carry out the mission that God gave them. In this chapter we also see what happens when people respond to the gospel and allow the Holy Spirit to work in their lives. People were speaking in other languages and many miracles were happening and lives were being changed. We see at the end of chapter 2 that 3000 people were saved after just one sermon. We also see that the Lord continued to add to that number day by day and we are continuing to see that this very day.
