No, we are not talking about capital in terms of money.  We are talking about the spelling of Neighbor with a capital "N".

Why do we capitalize Neighbor?

It is simple. Neighbors are the most important people around you. They are not merely people who populate a housing tract. They are individuals, people, and human beings with unique stories that belong to them.

This is why we spell Neighbor with a capital "N". To recognize their importance to the world, the neighborhood, and us. Most importantly, we must acknowledge that each one is an image bearer of God and their value and worth in the eyes of God.
