Here is an excerpt from a message by Shawn Bolz that I thought was really powerful:

If we really have a heart to see the kingdom dimension break in we’ll care about the poor, we’ll care about the orphans, we’ll care about the widows. You can’t have a heart for heaven without having a heart for justice, because when you see heaven you start being an answer to injustice on the earth. There’s all the ministries that are doing it with humanism that God’s about to radically invade with his Spirit from heaven. They’re going to see things in an unprecendent way and we’re going to go ‘Why is God touching all the ministries to the poor? Why not us?’ Because if you’re touching the poor you’re touching heaven. And if you’re touching heaven you’re touching the poor.

Why was it safe to give money to the apostles in the New Testament? Because they didn’t spend it on buying the biggest buildings in town. They didn’t spend it on doing their own thing and their own network. But you go into nine out of ten apostolic movements and they are so self seeking and self absorbed and it’s not safe to give your money in that context. So we have to have discernment as believers where we give.
