God has a purpose in all Israel not obtaining salvation. The purpose is for the salvation of the gentiles and to make Israel jealous that they might long for salvation.

Questions:
1. Does our faith make people jealous?
2. If we don't feel like the world is jealous of our salvation, why aren't they?

That the world would be jealous should not make us arrogant - remember we're saved by grace!
