Most grandparents are old already. They’re past the prime of their lives and it starts to show as illness and poor health. If you want to ask God to bless your grandparents with a long and happy life you can use this prayer:
Dear God
My grandparents are getting old now and I can see the effects of old age taking hold.
Please be with them as they get older.
Please take away their pain and ailments so that they may live a long and happy life.
I ask this for them because they mean so much to me.
They deserve the best and they deserve a long and happy life as they get older.
Please make this possible for them.
Amen
