A Study of Christian Assurance, Doctrine, and JoyAre you a Christian who has ever struggled with the assurance of your salvation? Many believers live with an underlying anxiety, wondering if they are truly "in the faith". The Apostle John, "the Elder," wrote his three short letters not just to combat heresy, but to graciously provide rock-solid confidence to every genuine child of God.In Letters from the Elder, Josh Davis walks you through the Johannine Epistles (1 John, 2 John, and 3 John) to help you take God's tests for assurance of real, lasting faith. This is not a book about earning salvation; it's about recognizing the clear, undeniable evidence-the good works-of a life already transformed by grace.In this study, you will: Discover the Core Tests of 1 John: Learn to examine your life using John's essential tests-including the Test of Confession, the Test of Obedience, the Test of Love, and the Test of Doctrine-to confirm the reality of your regeneration.Anchor Your Hope in the Incarnation: Understand the deep necessity and theological truth of the Hypostatic Union (Christ being simultaneously fully God and fully man). This reality makes his propitiatory death possible and allows Him our Kinsman-Redeemer, the only one who is both able and legally qualified to save us.Embrace Continuous Cleansing: Find rest in the assurance that the blood of Jesus Christ provides ongoing, continuous cleansing for your daily failures. Your standing is secured by Christ's perfect provision, not your perfect performance.Establish Boundaries of Truth (2 John): Be equipped to identify the spirit of the antichrist and learn why correct beliefs about Jesus are non-negotiable. These studies reveal the beautiful gift of hospitality, but also the boundaries and to not welcome false teaching.Fulfill the Mandate for Missions (3 John): See the church's calling to good stewardship and active support of missions. You will also be warned against the divisive sin of pride by studying the destructive example of Diotrephes.You don't have to live in spiritual uncertainty. The perfection of Christ's provision is the only basis for the imperfect believer to move forward. Open the pages of this book to be challenged, convicted, encouraged, and equipped to be a faithful ambassador for Christ. Gain the assurance of your salvation and be an agent of truth in a world full of lies.
