Jesus Christ is both the missionary God and the human representative who fulfilled the mission for which we were created. The whole story of the Bible turns on the merciful determination of this Triune God to redeem and to restore sinful creatures and the creation that lies in bondage because of the curse. In spite of every failure, disloyalty, and unfaithfulness of the human partner in the covenant, God will complete his mission. And in the person of Christ, he has also fulfilled the mission that he assigned to humankind in Adam: to lead creation into the everlasting blessing of immortality, forgiveness, righteousness, andpeace.
