Hi Grace,
Welcome to CC!
I do an online bible study. It takes an hour of study each day so I like that I'm busy learning God's word. I usually do 2 at a time.
I really don't enjoy watching very much tv. We have netflix only and have purchased some dvd's, but I'd rather go and walk the mall with friends or visit over tea or coffee at B&N than sit and watch tv.
When the arthritis allows, I crochet. I love crocheting doilies. Other things too like a dish cloth and towel set, afghan, amigurumi, etc.
You can go to Voice Of The Matyrs website and write letters to the persecuted church. Volunteer at church, the hospital or soup kitchen? Volunteer at your local prolife organization? Gospel Rescue Mission?
