The book of 1 John is an amazing book, the heart of the book teaches the foundations of the teachings of Jesus in simplicity. He also instructs the church concerning the spirit of antichrist which was already in the world, and not to be deceived. He wrote to all levels of the church by including the children, fathers and young men though I don't think this was necessarily a reference to age, but rather maturity in Christ. In the posts that follow I will go through each chapter of the book. Keep in mind that it is important that you understand the whole book is one message, one complete thought. I often find that people quote certain scriptures to validate their beliefs rather than let God reveal the wisdom and understandings contained in the book as a whole. That my friends is another message in itself.
