The first thing that has to be recognized is that one cannot train someone to be passionate--it's either in their DNA or it's not.

God is not some lesser employee, as many try to make Him out to be: rather He is the ultimate Treasure. He works in a man; He works on a man; He works through a man; He works around a man. Know that He does far more than simply work for a man. And yet, even as He Himself needs no one else, everyone else is ever in need of Him.

Do not instigate or treat any of your employees, working at your place, with contempt. Treat everyone with respect. You never know what benefit a person will bring.
