Neighborliness is a fruit of the gospel. The gospel is about the righteousness of Christ applied in the lives of His followers. That righteousness reaches out to guide others around us and to love them with God's love. That would then mean that Christians care for their neighbors. We must love the people all around us. If we don't, who will?
This simple proverb warns us that fallen, sinfilled people will not have righteous motives in their attempts at neighborliness. Ultimately they may lead others astray. It is the gospel at work in believers that lights up our communities with hope, real care, and meaningful love. Nothing else will do that.
Christians must let the gospel bridge the distance in our neighborhoods. We can see Christ bring people together. We can care because righteousness is our guide. We can serve our community with the love of Christ, starting with the people right next door. If we don't, who will?
