The phrase "No King But Christ" highlights the idea that Jesus Christ, the anticipated deliverer of the Jewish people and the saviour of humanity, is the ultimate authority and the supreme King of the universe (Ps 103:19-21, Ps 89:27, Col 1:16-18). All earthly governments are in direct conflict with His Kingdom (Dan 2:44, Rev 11:15). "No King But Christ" emphasizes the division between Church and the State. It reminds believers that we are citizens of His heavenly Kingdom, so we should not be entangled in the affairs of any state. The phrase encapsulates life in the Kingdom of God, which is spoken about throughout the Scriptures.

All people are made in the image of God, possessing qualities and attributes that reflect the nature of God, giving each individual inherent significance, dignity, and value (Gen 1:26-27, Ps 8:4-5, Ps 100:3, Gal 3:28). Humanity was created as God's handiwork with the purpose of bringing earth under His reign (Gen 9:7, Eph 2:10) through community in the body of Christ (1 Cor 12:12-27, Eph 3:10, Phil 2:13). After the fall separated people from God's presence, the Old Testament prophets looked forward to the coming of a kingdom where God would reign over all things, humanity included, bringing justice and peace to the world (Isaiah 9:6-7). When Jesus, the anticipated Messiah, finally came, He made a way for people to return to God (John 3:16, Mark 10:45, Rom 5:8).

The Kingdom of God is a central theme in the teachings of Jesus and the New Testament (Matt 4:17, Mark 1:15). The gospel proclaims that salvation and the reign of God have come near through Jesus' life, death, and resurrection resulting in the presence of God's Kingdom. His Kingdom is not limited to a particular geographic location or political entity; instead, it is a physical and spiritual reality that transcends all boundaries (John 18:36). The Kingdom of God is a state of peace, justice, and righteousness where God's will is done on earth (Matt 6:10). In the New Testament, the apostle Paul teaches that the Kingdom of God is a present, growing reality in the lives of believers, which will be fully realized in the future when Jesus returns (Eph 4:24, 1 Cor 15:24-25) and completes His original restorative purpose for creation (Rev 21:5). Furthermore, the New Testament paints all believers in Jesus as citizens in the Kingdom of God (Acts 28:31, Phil 3:20-21) called to live as ambassadors of His kingdom (2 Cor 5:19-20), reflecting its values and principles in their daily lives (Matt 6:33, Col 1:13, 1 John 3:16-17 Eph 5:1-2), and overcoming evil with good (Rom 12:17-21).

Jesus emphasized that in the Kingdom of God, the greatest rule is to love God and one's neighbour, saying that these two commandments sum up all of God's law and the prophets (Matt 22:37-40, Mark 12:31, Phil 2:3-8). In the Sermon on the Mount, which could be viewed as a kingdom manifesto, Jesus teaches his followers to go so far as to love their enemies, turn the other cheek, and bless those who persecute them (Matt 5:38-44, Luke 27:28). His teaching set a high standard. It stands in opposition to "Just War Theory", and all forms of state coercion (taxation is theft) and violence; after all, one can hardly lovingly threaten or kill their neighbour or enemy. The military's role undermines God's will for people: to love their enemies, feed them, clothe them, pray for them, bless them, and never repay evil for evil. The early Church understood this and was largely pacifist. As a result, many early Christians refused to serve in the military and suffered persecution rather than engaging in violence.

Today too, God's people reject all participation in human governments. We do not pledge allegiance to our state or wave its flag; to do so is an affront to Jesus. Rather, we live as foreigners in these nations, holding more in common with foreign believers than non-believing countrymen (Heb 11:13, Eph 2:19, 1 Peter 1:17, 1 Peter 2:9-11).

The message of the Kingdom of God is a powerful challenge to the coercive political and military power structures of all states and the powers of darkness that rule them. The nations of the world are governed by the lesser, rebellious gods (Deut 32:8-9, Ps 82:1, Ps 86:8, Ps 95:3, Ps 96:4, Ps 136:2). However, despite their prideful opposition to His ways, God regards the nations of the world as less than nothing (Dan 4:35).

In conclusion, "No King But Christ" is a powerful and transformative message rooted in Biblical truths. It reminds us that Christ is the ultimate authority and King over all and that His reign is far superior to that of any earthly government. When believers trust in Christ and walk in love, forgiving one another and meeting each others’ needs, they can experience the transformative power of His rule, reflecting His sovereignty and authority over all creation. The Kingdom of God is not just a future hope but a present reality that is growing and expanding in the lives of believers as they count themselves as citizens of heaven, follow Jesus and participate in his mission to bring about God's reign of love, justice, and peace.
