Resources for Godly Grandparents

I thought this short list of articles from Focus on the Family had some good thoughts.

I'm sure that these two FamilyLife broadcasts would have good stuff in them (but I haven't had a chance to listen to them myself).

The Second Half: Grandparenting Well (With Howard Hendricks)
Becoming a Great Grandparent

I'm sure, in the same way, that this DVD from Tim Kimmel is good:

Grandparenthood: More than Rocking Chairs

These two books were recommended by others, but I haven't read either of them to know if they are good.

The Power of A Godly Grandparent
The Gift of Grandparenting

I also enjoyed this sermon I found through Google.

Let me know what resources you've found to be helpful!
