Jesus who had been resurrected appeared to many people, for forty days. And, he went up the Mount of Olive, and said his last word, lifting his hands up and blessing all of them. 

He came back to Jerusalem and told the people to wait for what God has promised. 

"John was baptized with water, but you will be baptized with the Holy Spirit. Don't leave Jerusalem but gather here to pray, waiting for the Holy Spirit to come upon you." You will have to let the Holy Spirit baptize you, and preach everywhere with the Holy Spirit, to the ends of the earth."

After Jesus had talked with them, he was taken up to the Heaven, as they watched him. 

They had their eyes fixed on the sky, and then, two angels dressed in white said, 

"Galileans, why are you looking up at the sky? Jesus will come back in the same way that you saw him go to the Heaven."  

They came back, with joy, reminding themselves of what Jesus said. 

"Don't worry. Believe in me. Your faith in me believes in my Father God. There are a lot of place in my Father's home for me to stay. I'll go and find the place for you to stay." 

We have to deliver what the Lord said, waiting for Jesus to come back to us. 

(Matthew 28:16-20, Mark 16:15-20, Luke 24:44-53, Acts 1:3-11)
