How do we know the Kingdom of Heaven is true?

The truth of the Kingdom of Heaven is grounded in the revelation of Jesus Christ, who came from Heaven to declare the gospel. Throughout the New Testament, He emphasizes that the Kingdom is not of this world and is spiritually discerned, requiring faith in His promises. The prophetic fulfillment seen in both the Old and New Testaments, particularly in Christ's atoning work, assures us of the reality of this Kingdom. Specific passages, such as John 14:2, underscore that Jesus prepares a place in His Father’s house for His people, reaffirming the eternal promise of the Kingdom. Therefore, the assurance lies in Scripture and the work of Christ in redemptive history.
