It means that God's kingdom is governed by His love, which is expressed through grace and informs how believers interact with Him and one another.
The phrase 'love rules His kingdom' encapsulates the sovereign grace under which God's people live. This concept is rooted in the sacrificial love of Christ, which embodies the essence of God's will for His creation. Unlike the kingdoms of this world that rule through fear or coercion, God's kingdom operates through the principle of love. This results in a relationship of grace where obedience stems not from obligation but from a loving response to the grace received through Christ. Discipleship in this kingdom is characterized by joyful submission and heartfelt service, reflecting the love that God has for His people and which they reciprocate to Him and each other.
