How do we know God's kingdom is everlasting?

The everlasting nature of God's kingdom is a central tenet of Christian theology. Prophetic writings, such as those found in Isaiah, point towards a kingdom that will endure eternally: 'Of the increase of his government and peace there shall be no end' (Isaiah 9:7). Furthermore, Jesus' resurrection is a pivotal event that secures the reality of this kingdom, affirming that He reigns in power and His dominion will last throughout all generations. The assurance of this eternal kingdom is a source of hope, reflecting God's unchanging character and promise to His people.
