But when the fullness of time had come, God sent forth his Son, born of woman, born under the law, to redeem those who were under the law, so that we might receive adoption as sons. Galatians 4:4-5
It is extremely important, therefore, to keep in view and always to consider this statement, so delightful and full of comfort, as well as others like it which define Christ properly and accurately; for then throughout our life, in every danger, in the confession of our faith with a sure and steady confidence: “Law, you have no jurisdiction over me; therefore you are accusing and condemning me in vain. For I believe in Jesus Christ, the Son of God, whom the Father sent into the world to redeem us miserable sinners who are oppressed by the tyranny of the Law. He poured out His life and spent it lavishly for me. When I feel your terrors and threats, O Law, I immerse my conscience in the wounds, the blood, the death, the resurrection, and the victory of Christ. Beyond Him I do not want to see or hear anything at all.”
This faith is our victory (1 John 5:4), with it we conquer the terrors of the Law, of sin, death, and every evil, though not without a great struggle. Luther’s Works 26, 369
