The following is from the introduction of C. H. Spurgeon's message Turn Or Burn. His text for the message was, If he turn not, he will whet his sword; he hath bent his bow, and made it ready. Psalms 7:12
"If the sinner turn not, God will whet his sword. So, then, God has a sword, and he will punish man on account of his iniquity. This evil generation hath labored to take away from God the sword of his justice; they have endeavoured to prove to themselves that God will 'clear the guilty,' and will by no means 'punish iniquity, transgression, and sin.' Two hundred years ago the predominant strain of the pulpit was one of terror; it was like Mount Sinai, it thundered forth the dreadful wrath of God, and from the lips of Baxter or a Bunyan, you heard most terrible sermons, full to the brim with warnings of judgment to come. Perhaps some of the Puritan fathers may have gone too far, and have given too great a prominence to the terrors of the Lord in their ministry; but the age in which we live has sought to forget those terrors altogether, and if we dare to tell men that God will punish them for their sins, it is charged upon us that we want to bully them into religion, and if we faithfully and honestly tell our hearers that sin must bring after it certain destruction it is said that we are attempting to frighten them into goodness. Now we care not what men mockingly impute to us; we feel it our duty, when men sin, to tell them that they shall be punished; and so long as the world will not give up its sin, we feel we must not cease our warnings. But the cry of the age is, that God is merciful, that God is love. Ay, who said he was not? But remember, it is equally true, God is just, severely just and inflexibly just! He were not God, if he were not just; he could not be merciful if he were not just, the punishment of the wicked is demanded by the highest mercy to the rest of mankind. Rest assured, however, that he is just, and that the words I am about to read you from God's holy word are true: 'The wicked shall be turned into hell, and all the nations that forget God;' 'God is angry with the wicked every day;' 'if he turn not, he will whet his sword; he hath bent his bow, and made it ready. He hath also prepared for him the instruments of death; he ordaineth his arrows against the persecutors.' Forsooth, because this age is wicked, it is to have not hell; and because it is hypocritical, it would have but feigned punishment. This doctrine is so prevalent as to make even the ministers of the gospel flinch from their duty in declaring the day of wrath. How few there are who will solemnly tell us of the judgment to come. They preach of God's love and mercy, as they ought to do, and as God has commanded them; but of what avail is it to preach mercy unless they preach also the doom of the wicked? And how shall we hope to effect the purpose of preaching unless we warn men that if they 'turn not he will whet his sword?' I fear that in too many places the doctrine of future punishment is rejected, and laughed at as a fancy and a chimera; but the day will come when it shall be known to be a reality."
