Apostles were filled with joy
Before Jesus returned to his Father in heaven, he appeared to his apostles one last time. It was then that Jesus shared some special news.
In Luke 24:44-49, Jesus explained to his friends the meaning of the words he had spoken to them before he died and was resurrected. He told them that everything written in Scripture about the Messiah had to be fulfilled -- how he would suffer and die and rise again three days later, and how "repentance, for the forgiveness of sins, would be preached in his name to all the nations, beginning from Jerusalem."
Jesus said that the apostles would be his witnesses. And he promised to send an advocate to help them in their ministry. That advocate -- or supporter -- was the Holy Spirit.
He also told his friends to stay in Jerusalem until he had sent the Holy Spirit upon them.
The Lord then led his friends as far as Bethany. He raised his hands and blessed them. As he blessed them, he was taken up into heaven.
The apostles were filled with joy. When they returned to Jerusalem, they could always be found in the temple praising God.
