How is God Using You?

It's exciting to see how God is moving all around us.  Just heard a testimony last week about how one small act of kindness, helped bring two people together who would never have met otherwise.  How will God use this relationship? Will one lead the other to salvation in Jesus? Will one help the other in ways they didn't even know they needed help?  That's the point – isn't it?  We don't know what impact God has in mind when He prompts us to do one small thing.
