The teaching that Jesus Christ came in the flesh is of utmost importance, for it is the foundation of our forgiveness and our hope to one day be in God's Kingdom. If Christ had not come in the flesh to pay for our sins, there would be no propitiation, and we would remain in our sins. Yet, He came as a man, in a human body, to redeem mankind through His sacrifice. He, who is called Yahweh, the God of the Old Testament, did not cling to His equality with the Father but humbled Himself, taking the form of a human being as Jesus of Nazareth, the Son of God and Son of Man. He further humbled Himself in obedience, enduring crucifixion and abuse to pay for our sins, declaring at the end, "It is finished," as He gave up His spirit. Throughout His life as a fleshly human being, Jesus retained His essential personality and character as God, enabling Him to accomplish His redemptive work. He was born of a woman, conceived through the Holy Spirit, and lived among us, tabernacling with humanity. His disciples beheld His glory, full of grace and truth, shining through His goodness and truthful speech as the only begotten of the Father. John the Baptist testified that Jesus was the Lamb of God, tasked with removing sin from the world as a man, the literal Son of God through the impregnation of a human woman. Scriptural accounts in Matthew and Luke affirm His humanity, showing that He was born of Mary, a human woman, just as any other person, yet His Father being God made Him the Son of God and Son of Man. This unique nature qualified Him as the perfect Redeemer. Prophecies from Genesis and Isaiah foretold that the Savior would be the Seed of a woman, born of a virgin, embodying both human and divine natures as Immanuel, God with us, to save us from our sins. Paul emphasizes that Christ was born of a woman, subject to the law like any human, to redeem those under the law who had sinned. Peter confirms His humanity through self-evident proofs: Christ had blood, which He shed as a lamb without blemish; He was visible, able to be seen, felt, and heard; and He could die, unlike spirit beings, with God raising Him from the dead. John, addressing false teachings, asserts that he personally witnessed Christ's humanity, having seen, heard, and touched Him. He declares that those with the Spirit of God must confess Jesus Christ came in the flesh, for denying this undermines God's plan of redemption, rendering His sacrifice ineffective since only a human could pay for human sin. This truth, repeated across scriptures, is a mystery to many, but with God's Spirit, we understand that Christ was manifested in the flesh, witnessed by angels, Gentiles, and the world, and after His resurrection, received up into glory. His finished work as a human being, giving His body and blood, secures our forgiveness and salvation, fulfilling all that was necessary to be our perfect sacrifice.
