I would encourage you to read through this very short letter. Then, with pen & paper, go back and do a general overview of the topics presented. I believe you'll find an encouraging, challenging, outline of the life of the Christ-follower.
Often, new Believers are encouraged to begin their journey into God's Word starting with the Gospel of John, and that is well. But I would dare say that as an equal portion of that prescribed diet ...a new Believer should read John's own encouragement to the early church of who we are in Christ, how we faithfully serve a "loving" God, how to discern false teachings, the Christian worldview, and basically how to live the Christian life.
By no means "conclusive", I have provided my own recent review, with very brief topical headings below. Also, I have referenced supporting passages along with each theme / idea provided.....
