Repentance and forgiveness of sins will be preached in his name

Luke 24:36-53
Jesus is really has risen from the dead and alive. They see the crucifixion scars. He eats with them. He appears to peter, and the apostle is a new man. Despondency, mourning, fear are replaced by indescribable joy.
Jesus opened their minds so they could understand the Scriptures.
This is what is written: The Christ will suffer and rise from the dead on the third day, and repentance and forgiveness of sins will be preached in his name to all nations, beginning at Jerusalem.
Jesus lifted his hands and blessed them. While he was blessing them, he left them and was taken up into heaven.
Why?
We need God open our minds so we can understand the Scriptures.
Good News is the message of repentance and forgiveness of sins in Jesus name.
When Jesus died, they not only lost a much-loved friend and teacher, but he focus of all their hopes. They were alone and terribly afraid. Jesus had several times spoken no only of his coming dead but also of his resurrection, but they did not expect a sequel to the story.
Peter, the natural leader, was crushed beyond bearing by the knowledge that he had denied Christ.
Yet within 12 hours everything has changed. The tomb is empty - and Jesus himself has been seen on at least five different occasions, not only by the apostles but by other followers too.
They recognize hm s the real Jesus, not an ghost.
How?
Jesus has risen from the dead, so we have hope, we shall preach the gospel- repentance and forgiveness of sins to everyone under the name of Jesus Christ.
