How does Christ's humanity impact our understanding of His atonement?

The humanity of Christ plays a pivotal role in the doctrine of atonement. Since the atonement required a substitutionary sacrifice, it was necessary for that sacrifice to be made by one who is fully human. In Hebrews 2:14, we read that 'since the children have flesh and blood, he too shared in their humanity so that by his death he might break the power of him who holds the power of death.' This means that Christ’s death could only truly represent humanity because He took on human nature. Furthermore, His experience of temptation and suffering (Hebrews 4:15) ensures that He is an empathetic high priest for us. Without understanding that Christ came in the flesh, we miss the profound significance of His work in securing salvation for His people.
