coffee talk: guarding your heart

We're still Coffee Talking it up over here. God tells us in His Word to guard our hearts. I've wrestled with what that means for years. My tendency has been to take it to the extreme, letting little in or out of my heart. I know that isn't what God means, but I still don't have a very clear picture of what He actually does.

And so I ask you...

What does it mean to guard your heart?

Talk amongst yourselves.

(And while you're at it, will you also send up a prayer for my friend Amy who is giving birth to a baby girl today?)
