Walking with Open Hands

There is an expression "holding with an open hand" which, in the Christian circles I've been in, indicates a willingness to be open to God's plans, to be open to His choice for the future plans.
Similarly, I read something that brought that concept to a whole new level, beautifully said by Darlene Wilkinson in "Secrets of the Vine for Women":

I grew up believing that everything I love, treasure, enjoy and consider good on earth is a gift from God. But I didn't understand that every gift in this life has a time limit. People die, possessions can be destroyed, and positions taken away. That's just the way life is. And if I assume that everything I hold in my hand today is mine to keep, I will be deeply disappointed. Ultimately, I'll begin to question God's character and His intentions toward me - and that can spell big trouble.

So besides keeping my hands open, I've imagined a place for an expiration date written on the back of each treasure in my life. Then I leave it up to God to fill in that date. Why not? He is the only one who knows my future anyway. And He is the only one who knows what would be best for me.
