John Wesley warned not to waste one's time on those who will not hear.
That doesn't mean they won't some day hear, but it does mean not to beat your head against the wall.
Preach to the receptive.
Our small group is actually going to our local mall with a banner asking: "What is the significance of Easter" where we can get input from others, get a chance to chat and hand out whatever they'll accept.
We're also going to a local skate park where we'll BBQ food and offer it to the kids at the park and at the same time talk to them about God.
I'm looking forward to both events with great anticipation for what God will bring about. Of course, He already knows what will happen. ;-)
