Knowledge

Knowledge Without action and passion is dead.

1 Corinthians 8:1
Now about food sacrificed to idols: We know that “We all possess knowledge.” But knowledge puffs up while love builds up.

"Without knowledge action is useless and knowledge without action is futile".  - Abu Bakr

“Sentiment without action is the ruin of the soul.”  - Edward Abbey

Or even worse, speaking one and act another way.
