No matter how remarkable the message delivered by a prophet, an apostle, or a called man of God may be, that message must save the preacher himself as well as the people. Brother Singh asserts that the word of God cuts both ways. A two-edged sword (Hebrews 4:12) incises both the preacher's impurities and those of the congregation. The purpose of preaching is to change us, but many of us are reluctant to change. We prefer to serve God at our convenience.
