Why is the incarnation of Christ important for salvation?

The incarnation of Christ is essential for salvation as it allowed Christ to assume a human nature devoid of sin, which was necessary for Him to be the perfect sacrifice for sin. Without a sinless humanity, Jesus could not fulfill the law's demands or become the surety for His people, as His death had to satisfy divine justice. According to Hebrews 2:14-17, Jesus took on flesh and blood so that through His death, He could render powerless him who had the power of death, that is, the devil. Therefore, His incarnation ensures that He could relate to humanity while executing the plan of redemption for their sins in accordance with God's sovereign will.
