How can mere humans hope to understand and relate to an all-knowing all-powerful God who made the universe and everything in it? God’s ways are so much higher than human ways that they are impossible for humans to comprehend. So the only way for humans to reach out to God is for God to first reach out to them. The writer of the Letter to the Hebrews describes the lengths to which God went, in the second chapter:
Because God’s children have flesh and blood, he also became flesh and blood, so that through death he could destroy the one who had the power of death, that is, the devil, and rescue everyone who lived their whole lives as slaves to the fear of death. His help is not for angels; it is for the descendants of Abraham. He had to become like his brothers and sisters in every way, so that he could be a merciful and faithful high priest of God, to make atonement for the sins of the people. He is able to help people who are tempted because he suffered and was tempted.
In Jesus God became man, taking on himself all the characteristics and limitations of humanity. He experienced poverty and plenty, acceptance and rejection, love and alienation, joy and suffering in the same way as all humans do, yet without sinning. As the only human who did not deserve death as punishment for his own sins, he was able to die on the cross as the atonement for the sins of others, and it is only through Jesus that we can be reconciled to God.
