Why is it important for Christians to understand Christ's humanity?

The humanity of Christ is vital for several theological reasons. First, it affirms that He fully identifies with the human experience, having been made 'a little lower than the angels for the suffering of death' (Hebrews 2:9). This means that Christ knows our struggles and temptations. Secondly, because He was both God and man, He serves as the perfect mediator between God and humanity. Without His humanity, He could not have offered Himself as a sacrifice for our sins, as God's justice requires that satisfaction for sin be made by a representative of humanity. Thus, His incarnation was necessary for salvation. As the God-man, His righteousness and obedience are credited to believers, providing the basis for our justification before God.
