How do we know Christ was born to die?

Christ's birth is intrinsically linked to His purpose of death. In Galatians 4:4-5, it is stated that God sent His Son born of a woman, born under the law, to redeem those who were under the law. This shows that His earthly life was intended to culminate in His sacrificial death. Hebrews 10:12 elaborates that Christ, having offered one sacrifice for sin, sat down at the right hand of God, indicating the completion of His redemptive work on the cross. Thus, His birth should always be viewed through the lens of His ultimate purpose—to atone for sin and provide salvation to all who believe.
