If economic catastrophe does come, will it be a time that draws Christians together to share every resource we have, or will it drive us apart to hide in our own basements or mountain retreats, guarding at gunpoint our private stores from others? If we faithfully use our assets for his kingdom now, rather than hoarding them, can't we trust our faithful God to provide for us then?
When I save, I lay something aside for future need. If I sense God's leading, I will give it away to meet greater needs. When I hoard, I'm unwilling to part with what I've saved to meet others' needs, because my possible future needs outweigh their actual present needs. I fail to love my neighbor as myself.
God comes right out and tells us why he gives us more money than we need. It's not so we can find more ways to spend it. It's not so we can indulge ourselves and spoil our children. It's not so we can insulate ourselves from needing God's provision. It's so we can give and give generously (2 Corinthians 8: 14; 9: 11)
Giving up everything must mean giving over everything to kingdom purposes, surrendering everything to further the one central cause, loosening our grip on everything. For some of us, this may mean ridding ourselves of most of our possessions. But for all of us it should mean dedicating everything we retain to further the kingdom. (For true disciples, however, it cannot mean hoarding or using kingdom assets self-indulgently.)
