John continues to describe the qualities of the Children of God as he had described walking in the light. The children of God don’t just avoid sin, they obey God’s commands.
When we compare what John is writing here to what has come earlier in this text, this portion sounds not like a call to obedience, but rather like the test of love again. That is due to two things going on here. First, in this second half that I am calling the “God as Father” section, John also talks a lot about love and the fact that God is Love. You could just as easily talk about 1 John being divided into “God is Light” and God is Love” sections. But also, the five qualities that John listed for walking in the light—avoiding sin, obeying commands, not loving worldliness, the test of love, and keeping the faith—become a little muddled in this second half. They are not five individual qualities, but all aspects of what it means to be a follower of Jesus.
However, this section comprising the rest of chapter three is all about obedience. The pure “test of love” will come later, but here the commands of Christ are all summed up in the command to love. Just as Jesus summarized all of the Law and Prophets with “Love God and love your neighbor,” here John tells us that obeying the command to love one another covers every single instruction and demand God gives us.
To love is a command that we obey. This is not something the world or even Christians understand today. It is not a feeling, or a platitude. We are even told that we will have to exercise our obedience to love in the face of hatred; hatred from the world and hatred from those who claim to be followers of Jesus. And we do not get to isolate ourselves into a Christian ghetto and love people where we feel at ease and where we receive love in return. We love the way that we saw Jesus love: sacrificially, unselfishly, and whether it is returned or deserved or not.
Once again, this is an obedience and a quality that is beyond our ability. When we love as the children of God, it is with His power and help, not anything of ourselves.
