Why is the concept of Christ's dual nature important for Christians?

The dual nature of Christ, fully God and fully man, is vital for understanding the efficacy of His redeeming work. This theological concept ensures that He can represent humanity authentically while also possessing the divine authority to atone for sin. The burnt offering of fowls, described in Leviticus 1:14, illustrates this duality: while the neck of the fowl was pinched to shed its blood, the head—symbolizing Christ’s divinity—remains unsevered, showing the unity of His natures even in death.

Furthermore, this understanding reassures believers that Christ’s sacrifice was not merely the death of a mortal man but the substitutionary sacrifice of the God-man. This truth enables Christians to find confidence in their salvation, knowing that through Christ’s resurrection—affirmed by His presence with the Church through the Holy Spirit (as stated in John 14:3)—they are eternally secure. Embracing this dual nature deepens a believer's relationship with Christ, revealing the complexity of His love and sacrifice.
