How do we love God? Is it by doing things for him? Or is it by loving those he loves? Who does he love? He loves your neighbor, your enemy, those you know who love him (this is the one another Bit).
So Advent is a time to love. Serving. Putting aside things that divide. Praying for those who persecute you in different ways. These are what Jesus has taught us to do. So let us love.
