Charles Spurgeon said, "Sincerity makes the very least person to be of more value than the most talented hypocrite."
Leonard Ravenhill said, "Do you know why many people want revival? They want it to fill up the vacant pews. But many revivals empty the church before they fill it. God often wounds before He heals."
In their book, The Ten Greatest Revivals Ever, Elmer Towns and Douglas Porter share with us: "At the end of October, Evan Roberts took the train home to be with his family and conduct a week of meetings among the youth in his home church. From the train, he wrote various friends to tell them what he was doing and to solicit their prayer support. When he arrived in Loughor, he went to his pastor to request permission to conduct the meetings. The first meeting was scheduled, and he was given permission to speak to any youth who agreed to stay after the usual Monday evening meeting."
The word which is translated "sincerity" in our King James Bibles is used seven other times in the New Testament. Three of those times, it is translated as "incorruption."
