1 John 2:1-6 My little children, I am writing these things to you so that you may not sin. But if anyone does sin, we have an advocate with the Father, Jesus Christ the righteous. He is the propitiation for our sins, and not for ours only but also for the sins of the whole world. And by this we know that we have come to know him, if we keep his commandments. Whoever says “I know him” but does not keep his commandments is a liar, and the truth is not in him, but whoever keeps his word, in him truly the love of God is perfected. By this we may know that we are in him: whoever says he abides in him ought to walk in the same way in which he walked.
If we claim to be Christians, there ought to be something to show for it. If we aren’t walking a true Christian walk, obeying God, growing to be more like Christ, loving others; then we aren’t fooling anyone. If we love God, we’ll follow Him in everything we do.
All that said, we can try to obey in all things, but we will fail at times. We can’t be perfect, even though we should try to walk as closely to God as possible, with the help of the Holy Spirit. We’ll fail, but the true test is whether or not we admit to wrongdoing and ask forgiveness. If we say we don’t sin, again no one is fooled. We have to have a heart that’s humble enough to confess that we’ve sinned. This is what we’re called to as followers of Christ.
The best part is that we, as Christians, don’t receive God’s wrath for our sins, but we get forgiveness. Jesus already died in our place, He already took on our sins so that we don’t have to suffer the consequences. He made a way so that we have no reason to hold onto our sins as a secret and not admit to them. If we’ll just confess them, He’s faithful and just to forgive us (1 John 1:9). Jesus stands in the gap, advocating on our behalf, making our case. This isn’t just a message for seekers of truth; the gospel is for Christians too.
