John ends his little letter of 1 John by going back to what he has been saying all along. It may seem odd to end with "Little children, keep yourself from idols," but in that phrase we see the love that he has constantly shared and the theme that he has returned to again and again. Don't give up the faith! Don't buy the philosophy of your day. Don't give up on what you heard from the beginning. Don't buy the other offers of love and life from the would-be saviors around you. There is one God and one God alone and he has revealed himself in the incarnation, life, death and resurrection of Jesus - in the water, the blood and the Spirit.
