The term "His Son" in the Bible primarily refers to Jesus Christ, the Son of God. This designation underscores the unique and divine relationship between Jesus and God the Father, a central tenet of Christian theology. The concept of Jesus as "His Son" is foundational to understanding the nature of the Trinity, the incarnation, and the redemptive work of Christ.

Divine Sonship

The divine sonship of Jesus is affirmed in several key passages. In the New Testament, the voice of God the Father declares Jesus as His Son during significant events. At Jesus' baptism, a voice from heaven proclaims, "This is My beloved Son, in whom I am well pleased" (Matthew 3:17). Similarly, during the Transfiguration, the Father again affirms, "This is My beloved Son, in whom I am well pleased. Listen to Him!" (Matthew 17:5). These declarations highlight the divine approval and authority vested in Jesus.

Messianic Fulfillment

The title "His Son" also connects Jesus to Old Testament messianic prophecies. Psalm 2:7, a messianic psalm, states, "You are My Son; today I have become Your Father." This verse is echoed in the New Testament, emphasizing Jesus as the fulfillment of the promised Messiah. Hebrews 1:5 references this psalm, affirming Jesus' superiority over angels and His unique sonship: "For to which of the angels did God ever say, 'You are My Son; today I have become Your Father'?"

Incarnation and Humanity

The incarnation of Jesus as "His Son" is a profound mystery, where the divine takes on human flesh. John 1:14 declares, "The Word became flesh and made His dwelling among us. We have seen His glory, the glory of the one and only Son from the Father, full of grace and truth." This verse encapsulates the dual nature of Christ as fully God and fully man, essential for His role as the mediator between God and humanity.

Redemptive Mission

The mission of Jesus as "His Son" is intrinsically linked to the salvation of humankind. John 3:16, one of the most well-known verses, states, "For God so loved the world that He gave His one and only Son, that everyone who believes in Him shall not perish but have eternal life." This verse highlights the sacrificial love of God in sending His Son to atone for the sins of the world, offering eternal life to believers.

Resurrection and Exaltation

The resurrection of Jesus is a testament to His divine sonship and victory over death. Romans 1:4 declares that Jesus "was declared with power to be the Son of God by His resurrection from the dead: Jesus Christ our Lord." The resurrection affirms His identity and authority as the Son of God, and His exaltation is further emphasized in Philippians 2:9-11, where God exalts Him and bestows upon Him the name above every name.

Eternal Sonship

The eternal nature of Jesus as "His Son" is a key aspect of His identity. Colossians 1:15-17 describes Him as "the image of the invisible God, the firstborn over all creation. For in Him all things were created, things in heaven and on earth, visible and invisible." This passage underscores the preexistence and active role of the Son in creation, affirming His eternal nature and divine authority.

Relationship with Believers

Believers are invited into a relationship with God through His Son. Romans 8:29 speaks of believers being "conformed to the image of His Son, that He might be the firstborn among many brothers." This relationship is characterized by adoption, where believers become children of God through faith in Jesus Christ, sharing in His inheritance and glory.

In summary, the title "His Son" encapsulates the identity, mission, and eternal nature of Jesus Christ, central to the Christian faith and the understanding of God's redemptive plan for humanity.
