I don't lie. Neither do I dishonor parents, kill, steal, commit adultery or covet. I don't even hate. Do you? I doubt it. As Christians those old carnal laws are easy not to commit. What we need to grow in are motives, not hating, growing the fruit of the Spirit.
There are two kinds of sins. 1 John 3 is talking about the sins of lawlessness 1 John 3:4. Those are sins unto death. 1 John 5:16-17. It is the same as "the wages of sin is death." This type of sin is willful. They are in rebellion against God. They are of the heart and will. We choose to commit these sins, knowing full well they are against God's will for us. But as I just said, Christians find these not to their liking. It is not in the born-again nature to enjoy. But there again it is only Christians that have first repented and been baptized in the Holy Spirit. That is not automatic just because someone learns Jesus can keep them out of heaven. Just calling out "Lord, Lord" doesn't cut it. That is why Jesus said "I never knew you, you workers of lawlessness."
There is another type of sin which does not lead unto death. They are called trespasses, and are unwittingly committed, Leviticus 5:15. In the Lord's Prayer, we say, "And forgive us our trespasses, as we forgive them that trespass against us." The Reformation would teach in ignorance that "sin is sin." These unknown sins (to us) are what 1 John 1:7 refers to that are automatically cleansed by the blood of Jesus as we walk in the Spirit. They are also the sins referred to in 1 John 2:1. Jesus is our advocate when we miss the mark unwittingly. Notice, no reference to repentance is written in that verse, thus they are not willful sins. But, even these trespasses John says we can overcome and not sin at all. But that takes constant walking in the Spirit and growing mature fruit of the Spirit. Unfortunately, most of the Church today is from this church age - Laodecia. Most Christians today are lukewarm and unrighteous, always having itching ears to find teachers that will tell them they are saved, instead of the truth. Jesus tells them to repent. He is still on the outside of the Church. But He is what they need.
