Feel free to leave a comment about your favorite verse from Proverbs 14.
15 The naive believes everything, But the sensible man considers his steps.
There are so many areas of life where dishonest men try to -and often succeed - take advantage of the naive. Wisdom is needed in every area of life. I think a wise man/woman should study, have counselors, read books etc so wise decisions and clear direction in every area of life: spiritual, financial, mental, emotional, relational etc etc.
