You know that you were ransomed from the futile ways inherited from your fathers, not with perishable things such as silver or gold, but with the precious blood of Christ, like that of a lamb without blemish or spot. – 1 Peter 1:18,19

Martin Luther used to say that every sermon ought to have the doctrine of justification by faith in it. True; but let it have the doctrine of atonement in it. He says he could not get the doctrine of justification by faith in to the Wurtembergers’ heads, and he felt half inclined to take the book into the pulpit and fling it at their heads, in order to get it in. I am afraid he would not have succeeded if he had. But oh! how would I try to hammer again, and again, and again upon this one nail, “The blood is the life thereof.” “When I see the blood, I will pass over you.”

Christ giving up His life in pouring out His blood-it is this that gives pardon and peace to every one of you, if you will but look to Him- pardon now, complete pardon; pardon for ever. Look away from all other confidences and rely upon the sufferings and the death of the Incarnate God, who has gone into the heavens, and who lives today to plead before His Father’s throne, the merit of the blood which, on Calvary, He poured forth for sinners. As I shall meet you all in that great day, when the crucified One shall come as the King and Lord of all, which day is hastening on apace, as I shall meet you then, I pray you bear me witness that I have striven to tell you in all simplicity what is the way of salvation; and if you reject it, do me this favour, to say that at least I have proffered to you in Jehovah’s name this, His gospel, and have earnestly urged you to accept it, that you may be saved. But the rather I would God that I might meet you there, all covered in the one atonement, clothed in the one righteousness, and accepted in the one Saviour, and then together will we sing, “Worthy is the Lamb that was slain, and hath redeemed us to God by His blood to receive honour, and power, and dominion for ever and ever.” Amen. ~ C.H. Spurgeon
