I read a great blog post from Ben Stevens writing at the Gospel Coalition. His post, To Love Your Neighbor, You Must Know Your Neighbor talks about the way he and his wife got to know the neighbors in his new apartment complex. I liked the name of the post right out of the gate and apppreciated what he has to say. What I really liked was that nowhere in the article does it sound like this is strictly a ploy designed to get people to come to your church. Here is a snippet:
You cannot love your neighbor if you do not know that neighbor. Time spent with neighbors that does not result in conversions, does not result in spiritual conversation, or does not result in any greater appreciation of the work of Christ, is not a net loss. Let us be resolved to undertake this kind of work confident that it is a legitimate end unto itself, that our culture deserves our attention, and that God will call us to account for the time spent serving neighbors.
You should check it out, this is a great topic and one the church should embrace.
