While they were talking about this, Jesus Himself [suddenly] stood among them and said to them, “Peace be to you.” But they were startled and terrified and thought that they were seeing a spirit. And He said, “Why are you troubled, and why are doubts rising in your hearts? Look at [the marks in] My hands and My feet, [and see] that it is I Myself. Touch Me and see; a spirit does not have flesh and bones, as you see that I have.” After saying this, He showed them His hands and His feet. While they still did not believe it because of their joy and amazement, He asked them, “Do you have anything here to eat?” They gave Him a piece of broiled fish, and He took it and ate it in front of them.
Then He said to them, “This is what I told you while I was still with you, everything which has been written about Me in the [a]Law of Moses and the [writings of the] Prophets and the Psalms must be fulfilled.” Then He opened their minds to [help them] understand the Scriptures, and said, “And so it is written, that the Christ (the Messiah, the Anointed) would suffer and rise from the dead on the third day, and that repentance [necessary] for forgiveness of sins would be preached in His name to all the nations, beginning from Jerusalem. You are witnesses of these things. Listen carefully: I am sending the Promise of My Father [the Holy Spirit] upon you; but you are to remain in the city [of Jerusalem] until you are clothed (fully equipped) with power from on high.”
Then He led them out as far as Bethany, and lifted up His hands and blessed them. While He was blessing them, He left them and was taken up into heaven. And they worshiped Him and returned to Jerusalem with great joy [fully understanding that He lives and that He is the Son of God]; and they were continually in the temple blessing and praising God.
