Luke 5:17-26 - Who is this man?

I'm planning a talk/Bible study for sunday, here are my thoughts so far:

The Passage:
¹⁷ One day Jesus was teaching, and Pharisees and teachers of the law were sitting there. They had come from every village of Galilee and from Judea and Jerusalem. And the power of the Lord was with Jesus to heal the sick. ¹⁸ Some men came carrying a paralysed man on a mat and tried to take him into the house to lay him before Jesus. ¹⁹ When they could not find a way to do this because of the crowd, they went up on the roof and lowered him on his mat through the tiles into the middle of the crowd, right in front of Jesus.
²⁰ When Jesus saw their faith, he said, “Friend, your sins are forgiven.”
²¹ The Pharisees and the teachers of the law began thinking to themselves, “Who is this fellow who speaks blasphemy? Who can forgive sins but God alone?”
²² Jesus knew what they were thinking and asked, “Why are you thinking these things in your hearts? ²³ Which is easier: to say, ‘Your sins are forgiven,’ or to say, ‘Get up and walk’? ²⁴ But I want you to know that the Son of Man has authority on earth to forgive sins.” So he said to the paralysed man, “I tell you, get up, take your mat and go home.” ²⁵ Immediately he stood up in front of them, took what he had been lying on and went home praising God. ²⁶ Everyone was amazed and gave praise to God. They were filled with awe and said, “We have seen remarkable things today.”

Context!
Two weeks ago we looked at how the book that Luke wrote about the life, death and life of Jesus Christ on earth was all based on eyewitness accounts that he tirelessly sought out, so that he could make the most accurate account of Jesus that was possible, so that we can trust it. (Luke 1:1-4)

Last week we looked at John the Baptist, who warns people of their sin, and that the Son of God was going to come.

My thoughts
I'm thinking of doing something roughly along these lines:
- What does Jesus claim to do? - Forgive sins (verse 20)
- What does this mean about who Jesus is? - Either God, or a liar and blasphemer (verse 21)
- Who is he really? (verse 24, proves he is indeed God)
- How can we trust this to be true? (Luke 1:1-4, plus verse 17 (Pharisees and teachers of the law wouldn't rock up from every village of Galilee and from Judea and Jerusalem for nothing, and people at the time would easily have been able to confirm or deny what Luke was saying)
- What're the implications of this? - The Son of God came to earth! We need our sins forgiving, we need to find out what he came to say/do, we need to tell other people!

Then discussion points basically on that.

It's rough and early days, but there we go (:
