Standing Up for Kids

We'll fly around the world to aid children suffering from war or poverty, but we'll do nothing when it's a kid across the street. Rarely will Christians speak up for someone else's child caught in ongoing battles between their homes. We don't want to "get into their business" but we should do something. Respectfully, but assertively ask a parent who bad-mouths the other home and puts their child in the middle as a spy to stop. If it's about a child, it's not just "their business," it's ours.
