To say that God is love really isn’t enough. God is love embodied, and the love that he shares should be shared by those who live as Jesus did. John makes a good point: how can we love God who we can’t see, if we don’t love the neighbor we can see? It’s easy to love an idea, because ideas aren’t generally hard to live with. Sometimes God is just an idea, we make him safer than he really is. The intricacies of loving people in their messy complications are a great primer for loving an infinite God.
