What’s in a Name? The Significance of a Name and Belonging to Christ
Isaiah 44:5 reads:
“One will say, ‘I belong to the Lord’; another will call himself by the name of Jacob; still another will write on his hand, ‘The Lord’s,’ and will take the name of Israel.”
This verse speaks powerfully about identity, belonging, and the covenantal relationship between God and His people. It highlights how God’s people, in response to His grace and restoration, will declare their loyalty and allegiance in visible, public ways. The themes of identity and belonging that emerge from Isaiah 44:5 echo through the New Testament, particularly in the writings that describe belonging to Christ. These themes reflect the deep transformation of individuals who identify with God and find their ultimate identity and purpose in belonging to Him.
The Old Testament Context: Isaiah 44
Isaiah 44 is part of a larger section where the prophet speaks about God’s promise to restore Israel. It opens with reassurance that, despite Israel’s past failures, they remain God’s chosen people. The chapter paints a picture of hope and renewal, focusing on a future where God will pour out His Spirit upon His people, causing them to thrive.
In verse 5, Isaiah describes how individuals will respond to this divine blessing: some will declare, “I belong to the Lord,” others will identify themselves with the patriarch Jacob, and some will even write “The Lord’s” on their hands, marking themselves as belonging to God. This imagery speaks of a profound transformation, where people not only receive God’s blessing but also publicly and personally identify themselves as His.
Declaring Belonging to the Lord
The phrase “I belong to the Lord” is a bold declaration of identity. It signifies a deep, personal relationship with God. In ancient times, many nations worshipped false gods and idols, so to declare one’s allegiance to Yahweh set a person apart. This identification with the Lord is not merely superficial; it represents a covenantal commitment and a transformation of identity. Those who belong to the Lord are His possession, and this has profound implications for how they live and relate to the world.
This idea of belonging to the Lord carries forward into the New Testament, where it becomes central to the Christian understanding of salvation and identity in Christ.
The New Testament Understanding of Belonging to Christ
The New Testament expands on the theme of belonging to the Lord by emphasizing believers’ union with Christ. The writers, particularly Paul, describe what it means to belong to Christ in relational, covenantal, and transformative terms. Christians are not just individuals who follow a religious system; they are people whose entire identity is defined by their relationship with Christ.
1. Being “In Christ”
One of the most frequent ways the New Testament describes belonging to Christ is through the phrase “in Christ.” This reflects a profound spiritual union between the believer and Jesus.
• 2 Corinthians 5:17 states, “Therefore, if anyone is in Christ, the new creation has come: The old has gone, the new is here!” Being “in Christ” means that believers are no longer defined by their past or by the world’s standards. Their old identity has been replaced with a new one, rooted in their relationship with Jesus.
• In Galatians 2:20, Paul writes, “I have been crucified with Christ and I no longer live, but Christ lives in me.” This highlights the personal transformation that takes place when one belongs to Christ: the old self is crucified, and the believer’s life is now lived in union with Christ.
Being “in Christ” also places believers within a new community, the body of Christ, where they share in a collective identity and purpose.
2. Adoption as Children of God
The New Testament also describes belonging to Christ through the image of adoption. Christians are adopted into God’s family, becoming His children through faith.
• Romans 8:15-17 states, “The Spirit you received brought about your adoption to sonship. And by him we cry, ‘Abba, Father.’” This adoption signifies that believers are not only forgiven but are also cherished as children of God, with the privilege of calling God “Father.”
• Galatians 4:4-7 echoes this, describing how believers are redeemed and adopted into God’s family, making them heirs alongside Christ. This familial relationship emphasizes the security and intimacy that come with belonging to Christ.
In both passages, belonging to Christ is deeply relational, as believers are drawn into a close, personal relationship with God as their Father.
3. The Body of Christ
Belonging to Christ is also described through the metaphor of the Church as the body of Christ. This image highlights the interconnectedness of believers and their shared identity in Christ.
• 1 Corinthians 12:12-27 describes how each believer is a member of Christ’s body, with Christ as the head. Each person plays a unique role, and together they function as a unified body. Belonging to Christ, therefore, involves being part of this larger community, where individuals are interconnected and serve one another in love.
4. Purchased by Christ’s Blood
Belonging to Christ is also expressed in terms of redemption. Believers are described as being purchased by Christ’s blood, which highlights the cost of their belonging.
• 1 Corinthians 6:19-20 says, “You are not your own; you were bought at a price. Therefore honor God with your bodies.” This underscores the idea that belonging to Christ is not something believers earn, but something Christ secured through His sacrifice. The believer’s life is now lived in response to this costly redemption.
5. The Bride of Christ
Another metaphor used to describe belonging to Christ is that of the Church as the Bride of Christ. This imagery portrays a deep, covenantal relationship between Christ and His people.
• Ephesians 5:25-27 describes Christ’s sacrificial love for the Church, likening it to a husband’s love for his bride. Belonging to Christ means being cherished and loved with a covenantal commitment that is enduring and faithful.
Writing the Name on the Hand: A Visible Mark of Belonging
Returning to Isaiah 44:5, the image of someone writing “The Lord’s” on their hand symbolizes a visible, public declaration of belonging to God. This echoes themes of marking or sealing in the New Testament, where believers are often described as being sealed with the Holy Spirit as a mark of their belonging to Christ (Ephesians 1:13).
This mark of belonging is not just a private matter but something visible, impacting how believers live and relate to the world. Belonging to Christ transforms one’s identity and carries with it a sense of mission and purpose.
Conclusion: The Significance of a Name and Belonging
Isaiah 44:5 and the New Testament writings both emphasize the profound significance of declaring one’s belonging to God. Whether it is through the Old Testament language of identifying with the Lord, Jacob, or Israel, or through the New Testament’s depiction of being in Christ, adopted into God’s family, part of His body, or purchased by His blood, the theme of belonging is central to the believer’s identity.
To belong to God or to Christ is not merely a title or label—it is a transformation of one’s entire identity. It speaks of covenant, intimacy, and purpose. It carries with it the promise of God’s faithfulness and the responsibility to live in a way that reflects this profound relationship. Whether through the Old Testament imagery of writing the Lord’s name on one’s hand or the New Testament idea of being sealed with the Holy Spirit, belonging to God marks a person as His own—chosen, loved, and set apart for His purposes.
