Proverbs 4
A father passes on what his own father taught him when he was young and tender. Wisdom is to be loved and embraced, not just obeyed. The righteous path grows like dawn, "brighter and brighter," which is slow and gradual. Then the center: guard your heart, because life flows from it.
"The path of the righteous is like the first gleam of dawn, shining brighter and brighter until midday." (Proverbs 4:18)
"Guard your heart with all diligence, for from it flow springs of life." (Proverbs 4:23)
