What does 'Thy kingdom come' mean in the Lord's Prayer?

'Thy kingdom come' reflects a desire for the comprehensive reign of God, both spiritually in the hearts of believers and in the world at large. Jesus preached about the Kingdom of God, which is established through His work and is a manifestation of His authority and rule over all creation. This part of the Lord's Prayer is a plea for God's dominion to take effect, penetrating our lives and the lives of others, ultimately culminating in the fulfillment of His eternal kingdom. It shows the believer's longing for transformation, where God's will is done on earth as it is in heaven, aligning their desires with God's perfect purpose and His overarching authority over human affairs.
