There are many of those who accuse our Calvinist brethren of being cold-hearted toward evangelizing the lost. Well, apparently Charles Spurgeon missed that memo:

For the word of God is quick, and powerful, and sharper than any twoedged sword, piercing even to the dividing asunder of soul and spirit, and of the joints and marrow, and is a discerner of the thoughts and intents of the heart. (Hebrews 4:12)

To promulgate a dry creed, and go over certain doctrines, and expound and enforce them logically but never to deal with men’s consciences, never to upbraid them for their sins, never tell them of their danger, never to invite them to a Savior with tears and entreaties–what a powerless work this is! We want laborers, not loiterers.

Now; see what the laborer brings with him. It is a sickle. His communications with the corn are sharp and cutting. He cuts right through, cuts the corn down, and casts it to the ground. The man whom God means to be a laborer in his harvest must not come with soft and delicate words and flattering doctrines concerning the dignity of human nature and the excellence of self-help and of earnest endeavors to rectify our lapsed condition and the like. Such mealymouthedness may God curse, for it is the curse of this age.

The honest preacher calls a sin a sin and a spade a spade and says to men, "You are ruining yourselves; while you reject Christ you are living on the borders of Hell, and ere long you will be lost to all eternity. There shall be no mincing the matter; you must escape the wrath to come by faith in Jesus or be driven forever from God’s presence and from all hope of joy." The preacher must make his sermons cut. Our sickle is made on purpose to cut. The Gospel is intended to wound the conscience and to go right through the heart, with the design of separating the soul from sin and self, as the corn is divided from the soil.

(Charles Spurgeon, At the Master’s Feet, September 28)
