Help when someone needs help!  Saying “I’m praying for you” is helpful, but if you can be a person of action when someone needs you, that’s a great witness.  The single mom in your neighborhood whose baby-sitter didn’t show, the neighbor with the downed limb (you have a chain saw!), your friend’s grandchild who’s struggling with reading (you are a retired teacher!) – be there for them!  And when someone thanks you, it’s your chance to give God the credit.
