We know that we have come to know him if we keep his commands. Whoever says, “I know him,” but does not do what he commands is a liar, and the truth is not in that person. But if anyone obeys his word, love for God is truly made complete in them. This is how we know we are in him: Whoever claims to live in him must live as Jesus did.
Dear friends, I am not writing you a new command but an old one, which you have had since the beginning. This old command is the message you have heard. Yet I am writing you a new command; its truth is seen in him and in you, because the darkness is passing and the true light is already shining.
Anyone who claims to be in the light but hates a brother or sister is still in the darkness. Anyone who loves their brother and sister lives in the light, and there is nothing in them to make them stumble. But anyone who hates a brother or sister is in the darkness and walks around in the darkness. They do not know where they are going, because the darkness has blinded them.
Here’s how we can be sure that we know God in the right way: Keep his commandments.
If someone claims, “I know him well!” but doesn’t keep his commandments, he’s obviously a liar. His life doesn’t match his words. But the one who keeps God’s word is the person in whom we see God’s mature love. This is the only way to be sure we’re in God. Anyone who claims to be intimate with God ought to live the same kind of life Jesus lived.
My dear friends, I’m not writing anything new here. This is the oldest commandment in the book, and you’ve known it from day one. It’s always been implicit in the Message you’ve heard. On the other hand, perhaps it is new, freshly minted as it is in both Christ and you—the darkness fading away and the True Light already blazing!
Anyone who claims to live in God’s light and hates a brother or sister is still in the dark. It’s the person who loves brother and sister who dwells in God’s light and doesn’t block the light from others. But whoever hates is still in the dark, stumbles around in the dark, doesn’t know which end is up, blinded by the darkness.
John today might tell us that we need to get back to basics and live there. What is most basic about us and others around us in Jesus is not our political stance, as important as that is in terms of God’s kingdom and grace present in Christ. What’s most basic for us is our fellowship of love together in God the Father and in Jesus Christ. Nothing else matters in comparison.
When we make something else so basic and important that it divides us from other believers, and even alienates us from other people, that’s a sure sign that we’re off track. And when we actually descend into hatred of others, even those we consider enemies, we’re not obeying the clear commandment of our Lord to love them.
And if our lives don’t have the mark of Jesus on them, if we’re not living like Jesus did, then we need to ask ourselves and above all ask God what’s wrong. To live like Jesus is to be concerned about living in the light of God’s kingdom and grace present in Jesus. We measure our lives by King Jesus and his kingdom, and nothing else.
If anything gets in the way of any of this, we can be sure it’s darkness.
Something of what John might say to us today from this passage.
