How do we know that God's kingdom will come?

The assurance that God's kingdom will come is firmly rooted in biblical promises and prophecies. Passages such as Revelation 11:15 declare that 'the kingdom of the world has become the kingdom of our Lord and of his Christ.' This truth is reinforced by the call in Matthew 6:10 for His will to be done on earth as it is in heaven. Even in the face of opposition from false beliefs and systems, Christians are confident that God's purpose will triumph. David’s prayer in Psalm 72:19 is a bold proclamation that aligns with God's eternal plan — the day will indeed come when His glory fills the entire earth.
