To save one soul from eternal hell…

Then [Charlie] Peace (the notorious Sheffield criminal when he was about to be hung) is recorded to have said, “Sir, if I believed what you and the church … say you believe about heaven and hell—even if England were covered with broken glass from coast to coast, I would walk over it, if need be on my hands and knees, and think it a worthwhile living just to save one soul from an eternal hell like that.”

James Emery White, from Serious Times, p. 161

A soul is of countless price…

If there existed only one man or woman who did not love the Savior, and if that person lived among the wilds of Siberia, and if it were necessary that all the millions of believers on the face of the earth should journey there, and every one of them plead with him to come to Jesus before he could be converted, it would be well worth all the zeal, labor, and expense. If we had to preach to thousands year after year, and never rescued but one soul, that one soul would be full reward for all our labor, for a soul is of countless price.

Charles Spurgeon, quoted in One Thing You Can’t Do in Heaven by Mark Cahill p. 140
