What does the Bible say about Jesus becoming man?

In Hebrews 2:9-18, we see that Jesus was made a little lower than the angels for the suffering of death. This passage illustrates the mystery of God taking on human flesh to become our perfect mediator and savior. Christ's incarnation was essential for Him to relate to human suffering and to secure our redemption through His death. He embodies both divine and human natures, fully God and fully man, enabling Him to serve as our representative and high priest before God, thus completing the necessary sacrifice for our sins.
