Why is understanding the kingdom of God important?

Jesus preached that the kingdom of God is at hand, highlighting the transition from the Old Testament law to the new covenant of grace. In Romans 14:17, Paul explains that the kingdom of God is characterized by righteousness, peace, and joy in the Holy Spirit. This new kingdom represents a fundamental change in the relationship between God and humanity, allowing believers to experience God’s grace and mercy through faith in Christ. Thus, embracing this understanding helps Christians live in accordance with God’s will and anticipate the eternal fulfillment of His promises.
