Found this quote today as I prepare on 2 Timothy 4 for a conference I am going to next week - and very much looking forward to. Be even more excited if I was anywhere near ready.
This doesn't fit what I am doing but rather than lose it:
"Whatever you do, let the people see that you are in good earnest... You cannot break men's hearts by jesting with them, or telling them a smooth tale, or patching up a gaudy oration. Men will not cast away their dearest pleasures upon a drowsy request of one that seemeth not to mean as he speaks, or to care much whether his request be granted."
The Reformed Pastor, 1656. Quoted in Stott (BST), p.107.
