We are commanded to love our neighbors as ourselves. And who are our neighbors? Who are today's Samaritans? Perhaps they are the desperately poor congregating at the U.S. border to help their families survive. Perhaps they are our LGBT brothers and sisters, born differently and seeking respect and human kindness. Perhaps they are victims of a climate-change-related flood in a small island in the Pacific, their homes destroyed. Perhaps they are Ukranian refugees escaping a terroristic dictator willing to do anything to destroy them.
And we have our churches. Are they up to the task of helping all these people? If every Christian tithed would we have the clout to do 1% of what's needed in our world?
If our government disappeared, would you turn around and give every penny of your income, property, and sales taxes to your church to help provide for human needs?
Did Jesus tell us to "do what we can" but never to seek help from other entities?
You are free to believe what you wish about that, but I call it a gigantic cop out.
