John proclaimed one reason he wrote 3 letters to the early church was so that their joy might be made complete. He longed for the believers to have a truth of the knowledge of God and the good news of Jesus so that it would transform their lives. Pastor David teaches today, in this introductory overview lesson, that John wanted the church to recognize the lies and the liars so that they could walk in the truth of God and have full, abundant life. And this life is full of joy despite difficulties and daily trials.
