The question isn't were you challenged. The question is were you changed?
How can you have a dead service with a living Christ?
Prayer is as mighty as God, because He has committed Himself to answer it.
You never have to advertise a fire.
No man is greater than his prayer life. The pastor who is not praying is playing; the people who are not praying are straying. The pulpit can be a shop window to display one's talents; the prayer closet allows no showing off.
The Holy Book of the living God suffers more from its exponents today than from its opponents.
