What does the Bible say about God's everlasting kingdom?

Psalm 145:13 highlights the eternal nature of God's kingdom, stating, 'Thy kingdom is an everlasting kingdom, and thy dominion endureth throughout all generations.' This emphasizes that God's reign is not temporary or subject to change; it is sovereign, pervasive, and eternal. Throughout scripture, God's kingdom is portrayed as unshakable, with Christ seated at the right hand of the Father, having all authority in heaven and on earth. In Jesus, believers find assurance that they are partakers of this eternal kingdom, secured by His everlasting love and grace, as seen in passages like Ephesians 1:4-5.
