Walther on Salvation through Christ Alone

Luke 10, 26 ff. Christ meets the question of the self-righteous scribe with the counter-question: What is written in the Law? How readest thou? The scribe answers correctly: Thou shalt love the Lord, thy God, with all thy heart, and with all thy soul, and with all thy strength, and with all thy mind; and thy neighbor as thyself. And now Christ says to him: This do, and thou shalt live. The Lord, on this occasion, testified that, if salvation is to come by way of the Law, only he who fulfils the Law can obtain it. (By the way, we are not to think that to those who do the will of God, salvation must come as a reward of their merit. By no means; their salvation, too, would be owing to the goodness of God.) But to return to our discussion, the aforementioned condition which is attached to the Law hurls us into despair.

On a certain occasion, when the Lord wished to instruct the disciples as to what they must preach, He said: Go ye into all the world and preach the Gospel to every creature. He that believeth and is baptized shall be saved. Mark 16, 15. 16. This shows that no condition whatever is attached to the Gospel; it is a promise of grace.

The Atoning Death of Christ – Christianity & Liberalism: Machen

The atoning death of Christ, and that alone, has presented sinners as righteous in God’s sight; the Lord Jesus has paid the full penalty of their sins, and clothed them with His perfect righteousness before the judgment seat of God. But Christ has done for Christians even far more than that. He has given to them not only a new and right relation to God, but a new life in God’s presence for evermore. He has saved them from the power as well as from the guilt of sin. The New Testament does not end with the death of Christ; it does not end with the triumphant words of Jesus on the Cross, “It is finished.” The death was followed by the resurrection, and the resurrection like the death was for our sakes.  Jesus rose from the dead into a new life of glory and power, and into that life He brings those for whom He died. The Christian, on the basis of Christ’s redeeming work, not only has died unto sin, but also lives unto God.  Christianity & Liberalism by J. Gresham Machen, p. 114 book, p. 90 pdf below.
