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 the reader will accept these treasures. The Kingdom of Faith asks a significant question: "What is the highest goal of your life?" The Bible teaches that this goal is the growth of God's image within humanity, a promise that has never failed. A life conformed to the image of Jesus Christ brings great joy to humanity's Heavenly Father and glorifies him. Such a life invites the help of the Holy Spirit and carries eternal value in Jesus. This book encourages readers to see earthly life as a precious opportunity to think, speak, and live in a way that loves God and one's neighbor by faith. This reminds readers that "Our Father does far more abundantly than all that we ask or think, according to the power that works within us."
