2 Corinthians 8:4 (NLT)
They begged us again and again for the privilege of sharing in the gift for the believers in Jerusalem.
- Apparently the church in Jerusalem is experiencing some very tough times and the far-flung churches to whom Paul is ministering want to help out.
2 Corinthians 8:12-14 (NLT)
Whatever you give is acceptable if you give it eagerly. And give according to what you have, not what you don't have.
- Elsewhere, Paul equates generosity with faith. Generosity is an expression of faith. But here he adds a practical element, as he refers to faith as well as financial means.
 Of course, I don't mean your giving should make life easy for others and hard for yourselves. I only mean that there should be some equality.  Right now you have plenty and can help those who are in need. Later, they will have plenty and can share with you when you need it. In this way, things will be equal.
