Big 3 While We Wait: David's Failure

1. How does 2 Samuel 24:1 (where he Lord told David to take the census) match up with 1 Chronicles 21:1 (attributing the motive to Satan)

2. So God killed 70000 men as the result of a fairly harmless sin? Why not tell David before hand? Or punish David? Does it seem proportional/ fair to you?

3. Rox said “God’s mercy meets people’s greatest need”. But it was God’s angel who was killing people. Do we need God to save us from God? Is this the gospel?
