“And taking the twelve, he said to them, “See, we are going up to Jerusalem, and everything that is written about the Son of Man by the prophets will be accomplished. For he will be delivered over to the Gentiles and will be mocked and shamefully treated and spit upon. And after flogging him, they will kill him, and on the third day he will rise.” But they understood none of these things. This saying was hidden from them, and they did not grasp what was said.” – Luke 18:31-34
Here is a great video of Mark Driscoll where he gives six categories to help explain what Jesus meant in passages like the one above (the full message contains his full explanation).
3. Analogous service.
4. Events that prophesy the coming of Jesus.
5. Titles that refer to Jesus.
6. Old Testament prophecies about Jesus.
