This week, we finish chapter 4 of 1 John. Here, we see a command that has been one of the central themes to this book... love one another. But John doesn't just give the command, he also shows us that God is the source of all love and that he demonstrated an incredible and unnatural love by sending Jesus. John also shows that one of the best ways to know if we've experienced this love is that we are able to show the same unnatural love to others.
