Understanding the Sin Unto Death, Confidence in Spiritual Identity, and the Final Warning Against Idols Lesson 21 concludes our verse-by-verse journey through 1 John with some of the most sobering and eye-opening truths in the entire letter. In 1 John 5:16–21, the Apostle John deals with the mysterious topic of the “sin unto death,” urging us to walk in discernment, compassion, and holy fear. We’ll explore the boundaries of intercessory prayer, the danger of willful rebellion, the blasphemy against the Holy Spirit, and how a true believer stays protected and untouchable by the wicked one. But John doesn’t stop there—he reaffirms our identity as those born of God, gives assurance of understanding and eternal life through Christ, and closes with a sharp final command: “Keep yourselves from idols.” This lesson is essential for those who want to finish strong, walk in holiness, and remain deeply rooted in truth. Begin today and discover how to guard your heart, pray with purpose, and stand firm in your eternal identity!
