It is to the faithful flock who remained that John is writing to encourage and assure them that the gospel he preached, and the message by which they were saved, was the truth. He wanted them to know that they could be assured of their salvation through faith in Jesus, which manifested in their love for one another. As you can imagine, some in the church were conflicted. They were struggling to know with certainty that they were right to stay with John and the church, rather than going along with the deception of these persuasive teachers. To the faithful John says, “First of all, you can tell that they are wrong, because they do not live in the light according to the commandments of God, and second, because they are lacking in love.”
