According to John 6:39, John 5:30, psalms 130:8, Genesis 3:15, He came to redeem us. That means more than just buy us back but to return things to the way it was in the beginning, to make it so we can have a close relationship with God again such as they did in the Garden, So we can have salvation from the curse of sin and death, so we can be a part of the kingdom that was in the beginning. All of those were things that happened when he came but he came to redeem us. This is the answer.
