At first, Jesus' disciples did not understand. But after he had been given his glory, they remembered all this. Everything had happened exactly as the Scriptures said it would.
But the Holy Spirit will come and help you, because the Father will send the Spirit to take my place. The Spirit will teach you everything and will remind you of what I said while I was with you.
I am saying this to you now, so that when the time comes, you will remember what I have said. I was with you at the first, and so I didn't tell you these things.
Jesus was talking about the Holy Spirit, who would be given to everyone that had faith in him. The Spirit had not yet been given to anyone, since Jesus had not yet been given his full glory.
Jesus was taken up to sit at the right side of God, and he was given the Holy Spirit, just as the Father had promised. Jesus is also the one who has given the Spirit to us, and that is what you are now seeing and hearing.
The God that Abraham, Isaac, Jacob, and our other ancestors worshiped has brought honor to his Servant Jesus. He is the one you betrayed. You turned against him when he was being tried by Pilate, even though Pilate wanted to set him free.
We must keep our eyes on Jesus, who leads us and makes our faith complete. He endured the shame of being nailed to a cross, because he knew that later on he would be glad he did. Now he is seated at the right side of God's throne!
