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 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.
1 John 1:5-2:2
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.
1 John 1:5-2:2; MSG
John here is talking about the light believers in Christ are to be living in, in contrast to the darkness. It’s the light of God no less, the God who is light. Our walk in this world is to be in that light and in nothing else. C.S. Lewis pointed out, in that light we see everything else much clearer and for what it truly is. Anything other than that light is darkness. It doesn’t matter what it is, if that’s the “light” we’re living in, it’s actually darkness. And we’re sinning.
Yes, we maybe are no longer called “sinners” or “unrighteous” in Scripture, in fact we’re called “saints” or “holy people.” But this passage makes it clear that we still need a Savior. We still have sin, what I just heard a pastor call “sin sickness” in our lives which needs to be healed, or taken care of by God, not only legally, but fully.
We’re called to simply acknowledge our sins, ongoing, something which we’re to practice in our lives. At the same time John wants to help us to not actually commit the sin we would inevitably stumble into, left to ourselves. It’s a matter of walking in the light, in the light of the God who is light.
In this blessing we have a shared life, fellowship with one another as the blood of Jesus through his sacrificial death on the cross continues to cleanse us from all sin. When we do sin, as we confess it to God and when need be to those we’ve sinned against, that sacrifice of Christ takes care of it.
This is the reality in Jesus in which believers are called to live. To understand more fully what John is telling us here, we need to read the rest of the letter. But for the moment we’re let in on this marvelous reality for all of us in our individual lives and together. In and through Jesus.
