I'm another year older. Boy, how time does fly when you're having fun! I catch myself looking around this house where my grown kids were little and seeing one or another of them saying or doing something - like in a not so instant "replay". Leaves me with an ache. Still I wouldn't hold them back since everything I did was to get them ready for adult life and so they could get married and have their own families and be happy just like we were. (We're still are happy - even though I miss the members that have moved out from our home.)
The one thing that grinds on me is "what kind of relationship do they have with their God"? Is He in the center or outside the circle of their lives. Do they appreciate the sacrifice Jesus gave for them? Do or will their children know who He is? If we messed up in that area, nothing else we did is worth anything.
