Why is the incarnation of Christ essential for salvation?

The incarnation of Christ is fundamental to salvation because it was necessary for God to take on human flesh to redeem His creation. As stated in Hebrews 10:5, God prepared a body for Christ to fulfill the role of our substitute. Without this divine act, God could not simultaneously uphold His justice while offering grace. The union of divine and human natures in Christ allows Him to bear the sins of His people and fulfill the redemptive work needed for salvation. The incarnation is not simply a historical event; it's the fulcrum upon which God's salvation plan balances, showcasing His love and justice through the person and work of Jesus.
