Here’s an old poem by Edgar Guest that's worth reflecting on, especially for all of us who teach and preach others ...
I’d rather see a sermon than hear one any day;
I’d rather one should walk with me than merely show the way.
The eye’s a better pupil, and more willing than the ear;
Fine counsel is confusing, but example is always clear.
So I’d rather get my lesson by observing what you do;
It is not enough to preach it, you must live the sermon, too.
For I may misunderstand you and the high advice you give,
But there’s no misunderstanding how you act and how you live.
