He shall judge between the nations, and rebuke many people; They shall beat their swords into plowshares, and their spears into pruning hooks; Nation shall not lift up sword against nation, neither shall they learn war anymore. (Isaiah 2:4, NKJV)
As Isaiah lifted his eyes to gaze into the heavenly realms of God’s kingdom (ruled by Christ and announced to the world in the gospel), the prophet turned his attention to the effects the gospel would have when it was preached to the world (Mark 9:1; Matthew 28:18-20; Acts 1:8; 2:1-4, 36-41). The gospel of Christ pronounces God’s judgments and rebukes against sin and error (John 16:8-13). The result is glorious when sinners are convicted of sin and converted to Christ by the gospel of the kingdom. The house of God, the church, is a kingdom of peace with God and among men (Ephesians 2:14-22). Swords and spears – weapons of war used due to animosity and hatred – are turned into plowshares and pruning hooks – instruments of cultivation and harvest. Isaiah’s prophecy is not predicting a futuristic paradise earth. It is a portrait of enemies reconciled in the church, the kingdom of Christ. Instead of war, peace reigns as the Prince of Peace rules. In Christ’s kingdom we plant the seed of the gospel into hearts for a harvest of souls (Luke 8:15; Matthew 9:35-38; 1 Corinthians 3:6).
