This is the message we have heard from him and declare to you: God is light; in him there is no darkness at all. If we claim to have fellowship with him and yet walk in the darkness, we lie and do not live out the truth. But if we walk in the light, as he is in the light, we have fellowship with one another, and the blood of Jesus, his Son, purifies us from all[b] sin.
If we claim to be without sin, we deceive ourselves and the truth is not in us. If we confess our sins, he is faithful and just and will forgive us our sins and purify us from all unrighteousness. If we claim we have not sinned, we make him out to be a liar and his word is not in us.
My dear children, I write this to you so that you will not sin. But if anybody does sin, we have an advocate with the Father—Jesus Christ, the Righteous One. He is the atoning sacrifice for our sins, and not only for ours but also for the sins of the whole world.
This, in essence, is the message we heard from Christ and are passing on to you: God is light, pure light; there’s not a trace of darkness in him.
If we claim that we experience a shared life with him and continue to stumble around in the dark, we’re obviously lying through our teeth—we’re not living what we claim. But if we walk in the light, God himself being the light, we also experience a shared life with one another, as the sacrificed blood of Jesus, God’s Son, purges all our sin.
If we claim that we’re free of sin, we’re only fooling ourselves. A claim like that is errant nonsense. On the other hand, if we admit our sins—simply come clean about them—he won’t let us down; he’ll be true to himself. He’ll forgive our sins and purge us of all wrongdoing. If we claim that we’ve never sinned, we out-and-out contradict God—make a liar out of him. A claim like that only shows off our ignorance of God.
I write this, dear children, to guide you out of sin. But if anyone does sin, we have a Priest-Friend in the presence of the Father: Jesus Christ, righteous Jesus. When he served as a sacrifice for our sins, he solved the sin problem for good—not only ours, but the whole world’s.
My guess is that if John were here today with us, he might say something along the lines of why it’s essential that we walk in God’s light in Christ and see all other light as darkness. Where do we get our life from? Do we get it solely from Christ, or do we see something else as a necessary part of that light, or included in it?
We need to see everything, try to look at anything in the light of God in Christ. Therefore we view with a critical, by which I mean discerning eye all that is happening, noting what on the surface is good and what is not.
The only criterion by which we live is God’s light in Christ. We think and act and are accountable from that basis, and none other. Any divergence from it is considered a sin that needs to be confessed. And we in Jesus are in this together.
Just touching on what John might say to us today from this passage. I don’t think he would simply teach it as it is, and let it go at that. A good pastor takes note of the times, and seeks to guide the flock accordingly. In and through Jesus.
