For unto us a child is born, unto us a son is given: and the government shall be upon his shoulder: and his name shall be called Wonderful Counselor, The mighty God, The everlasting Father, The Prince of Peace. Isaiah 9:6
The child born in Bethlehem grew up to be Son given who took away the sin of the world. Jesus was born of a human to experience life like us, but was the fathered by the Holy Spirit in order to be the perfect sacrifice that would bring us into relationship with God.
If we have received Christ as our Savior, we have been crucified with Him and were raised up in newness of life! (Romans 6:4-7) At our co-crucifixion with Christ we became a new creation – a new person. Sure, we look the same and our personalities are the same, but we have a new spiritual DNA! He [God] made Him [Jesus] who knew no sin to be sin in our behalf, so that we might become the righteousness of God in Him. 2 Corinthians 5:21
We have been made righteous! We have been given the Holy Spirit to indwell us! We are joint heirs with Jesus. We are children of God. God is our Father. We belong to the family of God. We are citizens of Heaven. We can now identify with Christ. Our new Spirit is the Holy Spirit. We can now respond to life situations like Jesus did. We can now live and do only the things God tells us!
I’m NOT saying that we will live from our righteousness all the time, but we have the option to live like Jesus or live according to our flesh – our own knowledge. We have a new heart and a new Spirit and we can choose God’s way, just like Jesus did. (John 5:19; 12:49)
Of course we have some old beliefs and patterns and messed up thinking - unlike Jesus; but as we journey through life, we can rest assured that Jesus can identify with us because He knows how we feel. We identify with Jesus because we can choose to live dependent on our Father for our every word and deed.
