What does it mean that God became man?

The doctrine of God becoming man, known as the Incarnation, reflects God's profound love for humanity. In this act, God took on human nature, experiencing life's complexities, pains, and sorrows firsthand. This is not merely a theoretical concept; as stated in Hebrews 2:14-17, He shared in our flesh and blood to effectively become our representative. This incarnation allows Him to serve as a substitute for His people, taking on their sins, griefs, and sorrows. It underscores the depth of God's grace and mercy—truly, He came down to our level so that we might have eternal life.
