For a good introduction to Daniel you might want to listen to Tabitha Foley's Ten10 preach from last Sunday, but can I also encourage you to have a go at reading the book of Daniel for yourself this week.
The book splits into two halves.
The first six chapters tell six different stories:
- Daniel and his friends are tested
- Nebuchadnezzar's dream
- The fiery furnace
- Nebuchadnezzar goes insane and then recovers
- The writing on the wall
- Daniel in the lion's den
The book as a whole is dealing with the question of how do we relate to God and stay set apart for Him in a culture which is hostile to what we believe - sounds a lot like the world we live in.
