And all were astonished by the majesty of God. While they were all amazed at his every deed, he said to his disciples, "Pay attention to what I am telling you. The Son of Man is to be handed over to men." But they did not understand this saying; its meaning was hidden from them so that they should not understand it, and they were afraid to ask him about this saying. (Lk 9:43-45)
People were amazed at the majesty of God working in Jesus. They were all amazed at his every deed. People were wondering at the doings of Jesus. Mighty works of God were seen and they were performed by Jesus. People could only wonder at the way Jesus was going about. Wonder revealed the faith of the people and also the presence of the kingdom.
Jesus was very realistic. He was telling his disciples to py attention to what was going to happen in reality. Jesus was going to be handed over to the elders and leaders of the society and they in turn were going to crucify him. This was the reality which Jesus was worried about and he wanted the disciples to worry about. Future events were very important to Jesus.
The disciples did not understand what Jesus was talking about. The disciples were caught up the present reality which was very majestic and wonderful that the disciples had no time to worry about the future. They saw the might works in Jesus. They were all amazed at the miracles that they could not bother about the messianic presence and doings of Jesus.
