The parent who says they would die for their child but is willing to divorce for themselves doesn’t mean it.
Christopher Ash (on preaching, but applies to speaking in general as well):
We must not equate passion with style. But we must have hearts aflame with passion. Dr. Martyn Lloyd-Jones famously defined preaching as, “Logic on fire! Eloquent reason!… Preaching is theology coming through a man who is on fire.” The story is told that when W.E. Sangster was interviewing a candidate for the ministry, the nervous young man explained that he was quite shy and not the sort of person ever to set the River Thames on fire. “My dear young brother,” responded Sangster, “I’m not interested to know if you could set the Thames on fire. What I want to know is this: if I picked you up by the scruff of your neck and dropped you into the Thames, would it sizzle?” Never mind his eloquence; was he himself on fire?
Paul David Tripp:
Communication that attempts to find personal security by taking control forgets one of the sweetest provisions of the Word, God’s control over all things for his children. Another way to say this is that our words often reveal that we are not so much trusting in the Lord as we are trying to be him. We are attempting to do with our words what only he can do. When we do, we will fail, hurting ourselves and those around us.
The heart of the human problem is the problem of the human heart.
