Brian Bowman and Mathew Mueller talk about preparing to preach:

Proverbs 6:20–24

20 My son, keep your father’s commandment, and forsake not your mother’s teaching.

21 Bind them on your heart always; tie them around your neck.

22 When you walk, they will lead you; when you lie down, they will watch over you; and when you awake, they will talk with you.

23 For the commandment is a lamp and the teaching a light, and the reproofs of discipline are the way of life,

24 to preserve you from the evil woman, from the smooth tongue of the adulteress.
