Did John teach sinless perfectionism? Did he, by saying such things as, “whoever is born of God doesn’t sin” (1 John 5:18) assert what centuries later came to be called entire sanctification or Wesleyan perfectionism? According to this doctrine, Christians can attain a state of perfection in this life in which they completely defeat sin. Alternatively, other Bible teachers interpret John as merely saying that Christians no longer sin as a way of life or don’t sin willfully. Who’s right? Well, John, writing under the inspiration of the Holy Spirit, was right. And, maybe he wasn’t teaching either one of these things.
