"There are plenty of gifted communicators in the modern evangelical movement, but today’s sermons tend to be short, shallow, topical homilies that massage people’s egos and focus on fairly insipid subjects like human relationships, “successful” living, emotional issues, and other practical but worldly - and not definitely biblical - themes. Like the unbiquitous Plexiglas lecterns from which these messages are delivered, such preaching is lightweight and without substance, cheap and synthetic, leaving little more than an ephemeral impression on the minds of the hearers."
-John MacArthur (from his book "Fool's Gold?: Discerning Truth in an Age of Error")
2 Timothy 4:1-5: I charge you in the presence of God and of Christ Jesus, who is to judge the living and the dead, and by his appearing and his kingdom: preach the word; be ready in season and out of season; reprove, rebuke, and exhort, with complete patience and teaching. For the time is coming when people will not endure sound teaching, but having itching ears they will accumulate for themselves teachers to suit their own passions, and will turn away from listening to the truth and wander off into myths. As for you, always be sober-minded, endure suffering, do the work of an evangelist, fulfill your ministry.
