The phrase "Those who belong to Him" refers to individuals who have entered into a covenant relationship with God through faith in Jesus Christ. This concept is deeply rooted in the New Testament and is central to Christian theology, emphasizing the identity, privileges, and responsibilities of believers.

Biblical Foundation

1. Identity in Christ: The New Testament frequently speaks of believers as those who belong to Christ. In Romans 8:9, Paul writes, "You, however, are controlled not by the flesh, but by the Spirit, if the Spirit of God lives in you. And if anyone does not have the Spirit of Christ, he does not belong to Christ." This verse underscores the indwelling of the Holy Spirit as a defining mark of those who belong to Him.

2. Adoption as Children: Believers are described as adopted children of God, highlighting their new identity and relationship with the Father. Galatians 4:4-5 states, "But when the time had fully come, God sent His Son, born of a woman, born under the law, to redeem those under the law, that we might receive our adoption as sons." This adoption signifies belonging to God's family.

3. The Good Shepherd: Jesus uses the metaphor of the shepherd and sheep to describe His relationship with those who belong to Him. In John 10:14, He declares, "I am the good shepherd. I know My sheep and My sheep know Me." This intimate knowledge and care characterize the bond between Christ and His followers.

Privileges of Belonging

1. Eternal Life: One of the primary privileges of belonging to Christ is the promise of eternal life. In John 10:27-28, Jesus assures, "My sheep listen to My voice; I know them, and they follow Me. I give them eternal life, and they will never perish; no one can snatch them out of My hand."

2. Peace and Security: Believers enjoy peace and security in their relationship with God. Philippians 4:7 promises, "And the peace of God, which surpasses all understanding, will guard your hearts and your minds in Christ Jesus."

3. Inheritance: Those who belong to Christ are heirs of God's promises. Romans 8:17 states, "And if we are children, then we are heirs: heirs of God and co-heirs with Christ—if indeed we suffer with Him, so that we may also be glorified with Him."

Responsibilities of Belonging

1. Holiness and Obedience: Belonging to Christ calls for a life of holiness and obedience. 1 Peter 1:15-16 exhorts, "But just as He who called you is holy, so be holy in all you do; for it is written: 'Be holy, because I am holy.'"

2. Love and Service: Believers are commanded to love one another and serve others. In John 13:34-35, Jesus instructs, "A new commandment I give you: Love one another. As I have loved you, so you must love one another. By this everyone will know that you are My disciples, if you love one another."

3. Witness and Evangelism: Those who belong to Christ are called to be His witnesses. Acts 1:8 declares, "But you will receive power when the Holy Spirit comes upon you, and you will be My witnesses in Jerusalem, and in all Judea and Samaria, and to the ends of the earth."

Conclusion

The concept of belonging to Christ is a profound and multifaceted theme in the New Testament. It encompasses the believer's identity, the privileges they receive, and the responsibilities they bear. Through faith in Jesus, believers are adopted into God's family, assured of eternal life, and called to live lives that reflect their relationship with Him.
