the last best word

I like what Philip Yancey has to say about grace:

"As a writer, I play with words all day long. I toy with them, listen for their overtones, crack them open, and try to stuff my thoughts inside. I've found that words tend to spoil over the years, like old meat. Their meaning rots away. Consider the word"charity," for instance. When King James translators contemplated the highest form of love they settled on the word "charity" to convey it. Nowadays we hear the scornful protest,"I don't want your charity!"
Perhaps I keep circling back to grace because it is one grand theological word that has not spoiled. I call it "the last best word" because every English usage I find retains some of the glory of the original. Like a vast aquifer, the word underlines our proud civilization, reminding us that the good things come not from our own efforts, rather by the grace of God. Even now, despite our secular drift, taproots still strech toward grace listen how we use the word.
Many people "say grace" before meals, acknowledging daily bread as a gift from God. We are grateful for someone's kindness, gratified by good news, congratulated when successful, gracious in hosting friends. When a person's service pleases us, we leave a gratuity. In each of these uses I hear a pang of childlike delight in the undeserved.
A composer of music may add grace notes to the score. Though not essential to the melody- they are gratuitous- these notes add a flourish whose presence would be missed. When I first attempt a piano sonata by Beethoven or Schubert I play it through a few times without the grace notes. The sonata carries along, but oh what a difference it makes when I am able to add in the grace notes, which season the piece like savory spices."

Yancey expounds further, and I am tempted to continue quoting him! But he wrote the book (What's So Amazing About Grace?) so I wouldn't have to. Now that I've whet your whistle, you can go to the source yourself.
Grace is amazing in myriads of ways. My name (Nancy) means full of grace. How I like that! I have wriggled a dallop of grace into my email address (nkh.grace) also, just as a reminder. Now that it has been pointed out to me, I can remember His grace in everyday conversation. Or when I play Beethoven or Schubert. Or when I leave a tip.
