Jesus Christ is unique. There is no one like Him. He is God incarnate, both God and Man, theanthropic. In the incarnation, the eternal Son of God took on true humanity without surrendering His deity, becoming the God-Man forever. This is the hypostatic union: undiminished deity and true humanity united in one Person. He is fully God and fully man, with two distinct natures, neither mixed nor altered. His deity is eternal. His humanity was added in time. From the incarnation forward, both natures are permanently united in one Person, Jesus.

Eternal Life and the Faithfulness of Christ
The believer’s confidence about possessing eternal life is not grounded in self-effort but in the immutability of Christ’s person and promise. Eternal life is received the moment one believes in Christ, for “whoever believes in Him shall not perish, but have eternal life” (John 3:16b). Once received, eternal life becomes the unbreakable possession of all who trust in Jesus as Savior (John 3:16; 5:24). God’s integrity and righteousness are bound up in the keeping of His Word, and even “if we are faithless, He remains faithful, for He cannot deny Himself” (2 Tim 2:13). Believers are “sealed in Him with the Holy Spirit of promise, who is given as a pledge of our inheritance” (Eph 1:13–14), guaranteeing their final redemption. This means that eternal life is locked in forever. To doubt the permanence of eternal salvation is to question the reliability of the God who cannot lie (Tit 1:2; Heb 6:18).
The Doctrine of the Hypostatic Union
The doctrine of the hypostatic union is one of the most vital truths in Christology. Jesus Christ is one Person with two natures—undiminished deity and true humanity—inseparably united without mixture or loss of identity. Scripture testifies, “In the beginning was the Word, and the Word was with God, and the Word was God” (John 1:1), and further declares, “And the Word became flesh, and dwelt among us” (John 1:14a). Paul states, “For in Him all the fullness of Deity dwells in bodily form” (Col 2:9). These passages establish that the eternal Word, God the Son, took on true humanity in time, becoming the God-Man.
