The necessity of Christ's deity is foundational for the work of redemption, as it ensures His obedience to the law and the efficacy of His sacrifice.
The necessity of Christ's deity becomes evident in understanding the nature of redemption. The work Christ undertook required Him to be both fully God and fully man, as only through His divine nature could He fulfill the demands of God's law. His incarnation as a human—'God manifest in the flesh'—is essential because it serves as the foundation for His redemptive work. Such a basis guarantees the strength, permanency, and glory of the work, empowering His obedience to the law and the ultimate efficacy of His blood atonement. If He were merely of creature excellence, His sacrifice would lack the infinite worth required to reconcile sinful humanity to a holy God.
