INCARNATION refers to Jesus Christ coming "in the flesh." The eternal Son of God the Father assumed to Himself a complete human nature from the Virgin Mary. He was (and is) one divine Person, fully possessing from God the Father the entirety of the divine nature, and in His coming in the flesh fully possessing a human nature from Mary. By His Incarnation, the Son forever possesses two natures in His one Person. The Son of God, limitless in His divine nature, voluntarily and willingly accepted limitation in His humanity, in which He experienced hunger, thirst, fatigue-and ultimately, death. The Incarnation is indispensable to Christianity-there is no Christianity without it. The Scriptures record, "Every spirit that does not confess that Jesus Christ has come in the flesh is not of God" (1 John 4:3). By His Incarnation, the Son of God redeemed human nature, a redemption made accessible to all who are joined to Him in His glorified humanity.
