What is justification by faith?

Justification means the soul is transformed, made capable of face to \face vision of God: 2 Peter 1:4 and 1 Cor 13:12, and becomes Temple of Holy Spirit: 1 Cor 3:16 and 6:19. Faith includes three elements; cf answer 14. Luther thought justification left one totally corrupt, was only legal, and thought faith is just confidence merits of Christ apply to me. What did Paul say of Law? We are free from law in sense that keeping it does not earn salvation, which is an inheritance to children of God; but not free to violate it, if we do, we lose our inheritance: Rom 6:23, 1Cor 6-9-10.
