How do we know the kingdom of God is present?

Christ Himself stated, as recorded in Luke 17:20-21, that the kingdom of God is not something to be observed outwardly, but is instead present among us. The essence of the kingdom of God is the dominion of King Jesus, who reigns not just in a future heavenly realm, but actively through His church and in the hearts of believers. When individuals receive the gospel and submit to Christ’s lordship, they enter into this kingdom, enjoying the blessings that come from being under the authority of Christ. Furthermore, Psalm 2 affirms that God has established His King upon Zion, illustrating the current reign of Christ and His Kingdom.
