Zeal.
I think that I like this word.

It creates this protective aura of purity. Other cheap words on the street are willing to pay you to use them. But just as the word entails, zeal is better than that. Its high standards for itself won't let anyone take advantage of it. Whilest popular words like "passion" and "intensity" are casually passed around and beaten raw. Diligent in enthusiasm, zeal proudly won't settle for less than it deserves.

Zeal comes easy for only one...
Isaiah 42:13 The LORD will march out like a mighty man,
like a warrior he will stir up his zeal;
with a shout he will raise the battle cry
and will triumph over his enemies.

But we are called to be zealous...

Romans 12:9-13 Love must be sincere. Hate what is evil; cling to what is good. 10Be devoted to one another in brotherly love. Honor one another above yourselves. 11Never be lacking in zeal, but keep your spiritual fervor, serving the Lord. 12Be joyful in hope, patient in affliction, faithful in prayer. 13Share with God's people who are in need. Practice hospitality.
