The Reciprocal Truth of the Incarnation

On the Cross, we see the reciprocal truth of the Incarnation: Jesus Christ is not only God’s faithfulness toward us, he is also our faithfulness toward God. 

Just as one trespass [Adam’s] resulted in condemnation for all people, so also one righteous act [Christ’s] resulted in justification and life for all people. (Romans 5:18)

Where Adam was unfaithful and disobedient to God, resulting in death and corruption for all, our Lord Jesus Christ was faithful and obedient to God, resulting in justification and life for all. 

You should have the same attitude toward one another that Christ Jesus had, who though he existed in the form of God did not regard equality with God as something to be grasped, but emptied himself by taking on the form of a slave, by looking like other men, and by sharing in human nature. He humbled himself, by becoming obedient to the point of death – even death on a cross! As a result God highly exalted him and gave him the name that is above every name, so that at the name of Jesus every knee will bow – in heaven and on earth and under the earth – and every tongue confess that Jesus Christ is Lord to the glory of God the Father. (Philippians 2:9-11)

As fully divine, Christ did not consider being equal with God as something to be plundered and exploited, to be held on to at all costs, and used for his own advantage — Christ reveals that God is simply not like that! As fully human, Christ was fully obedient and faithful to God, even to the point of the shameful death of the Cross. So, by the Incarnation and the Cross, we see exactly what the faithfulness of God is, and what the faithfulness of humankind is — what it means to be God, and what it means to be human.
