The Justification and Kingdom of God series seeks to answer the question: "How can justified Christians in Jesus bear the fruit of faith, reflecting growth in God's image?" To address this, the series helps readers understand what happens to the image-bearers of God in Adam or in Jesus Christ. This reveals the deeper meaning of the gospel and the restoration of God's image, uncovering hidden treasures. Now, the challenge is whether you will accept these treasures. The Kingdom of the Covenant emphasizes the eternal kingdom of the living God through the lens of God's righteousness. This encourages readers to remember God's righteousness, which runs through his covenants, serves as the legal standard of governance, the standard of salvation, and the standard of a good life. Just as God's righteousness is the foundation of his word for his kingdom, God's word is the standard for wisdom, knowledge, judgment, and actions. Through his word, God opens the gates of heaven and connects the present reality of lives with the eternal nature of his kingdom. Now, lives of faith on this earth carry eternal consequences. This book asks, "What would you do with this gift—God's word?"
