"1 John - Be Real," is written by Warren Wiersbe. Here are guidelines to help us turn from hypocrisy to truth, because how you live means more than what you say. Hypocrisy and hide-and-seek games with worldliness hurt you and those around you. Many feelings that people fall into - sentimentality, emotionalism, and lust - are not love because real faith must be based on time-tested truth.
Here is a book, based on the First Epistle of John that shows you how to be the person you know God wants you to be.
