Bill Hybels, Senior Pastor at Willow Creek in Illinois helps define the 'diligent worker' in the book of Proverbs in the Bible:
"A Diligent worker...
Shows up on time
Determine what's expected
Exceeds expectations
Is joyful
Plays nice
Honors supervisor
Admits mistakes
Shares credit
Resolves conflict
Takes responsibility to get better
Honest with time"
So make sure you are a diligent worker and not a sluggard. After all it's the right thing to and it models the way for others.
