Love your neighbor as yourself

This is really what it's all about. There are really only two laws:
1. Love God.
2. Love your neighbor as yourself.
By "neighbor" Jesus means everyone; not just the people within close proximity to your residence but all people. I know that around Valentine's Day people spend a lot of time thinking about romantic love, but it's a good reminder to think of the truest most selfless love, that of Jesus giving His life for all of us to give us life.
