In the beginning of creation God said, "Let us make man in our own image and likeness" Gen 1: God was referring to the three persons , God the Father, God the Son, and God the Holy Spirit. It is not clear which part the three persons individually played in creating man. But we know for sure the Trinity worked together in forming man in their own image.
Man lost his relationship with God through Adam and Eve. God has to recreate man again but this time not from the dust but soul.
God the Father hatched the plan, (Matthew 1:20-22.) God the Son executed the plan by coming down to live among us. Jesus healed the sick, raised the dead, fed the people and offered Himself up for atonement for our sins. After Jesus' work was done, He said on the cross, “it is finished” The plan to recreate the new man is accomplished. Concerning the coming of the Holy Spirit Jesus said, “Nevertheless I tell you the truth. It is expedient for you that I go away, for if I go not away, the Comforter will not come unto you; but if I depart, I will send Him unto you.” The Holy Spirit comes to empower, supervise, manage and direct the recreated man. Unlike the first creation of man, the second creation shows distinct roles each of the Trinity played.
Since the Trinity work is inseparable it is impossible to pick or believe just one aspect of their work and think you have been recreated as a new man. You must believe that God had a plan to reconcile man, Jesus came down to fulfill the plan of reconciliation and the Holy Spirit is present in the recreated man directing him towards God's intended purpose.
