How do we know the spiritual kingdom is true?

The truth of the spiritual kingdom is grounded in the teachings of Scripture, particularly in passages like Luke 22:29 and John 18:36. These verses convey that Jesus appointed a kingdom that transcends worldly authority, focusing instead on a spiritual reign within the hearts of his followers. The existence of this kingdom is experienced by believers, who often find themselves strengthened during times of temptation and trials, thereby witnessing the grace of God at work in their lives.

Moreover, this spiritual kingdom stands as a fulfillment of God's promises, notably those found in the Hebrew Scriptures, such as in Daniel 2:44, where it is declared that God's kingdom will prevail over all earthly kingdoms. Through the inward work of the Holy Spirit, believers embody this kingdom of grace, experiencing righteousness, peace, and joy that only comes from a true relationship with Christ. Their testimonies of perseverance and spiritual transformation further testify to the reality of this kingdom.
