you can appreciate the gift of  grace if you understand that grace is expensive and indispensable.

if you come to a wedding party, and they give you a souvenir of picture frame, that free gift is not life changing simply because it is not expensive and not indispensable. is it free? yes. is it gift? yes. but not life changing. Indispensable: you already have picture frame. But even if you didn't have, it is extremely easy to get one.

but what if you are a poor person in need of operation, and the operation in that remote place is unobtainable and expensive. what if a person, that is not too rich, give up his asset and sell everything to pay for your surgery. This is indispensable, you have to got it. Expensive, because this person went to poverty to save you.

It is not the free-ness of the gift, but the cost and indispensable of the gift.
