When you preach, do not teach interesting things. Do not preach great information to help people’s lives be better/happier/fuller/richer/stable or anything!
PREACH as if you are speaking of LIFE and DEATH. Preach as if your message MUST be heard and lived out or they’ll die. We have had enough good speaches to improve our quality of LIFE. We must now PREACH A COMING KINGDOM, Not a convenient one now.
