Why did Jesus have to take on human nature?

Jesus had to take on human nature to accomplish two critical objectives: to satisfy Divine justice by living a sinless life as our representative and to serve as a compassionate High Priest who understands our sorrows. Hebrews 2:14 shows that by becoming human, He could identify with us in our struggles and sorrows, enabling Him to truly sympathize with our condition. The union of His divine and human natures is crucial, as it affirms both His ability to redeem and to empathize, forming the foundation of our hope in Him.
