There is a bible verse from 1 Thessalonians 5:18 that says "give thanks in all circumstances; for this is God's will for you in Christ Jesus".
I remember when I had an epiphany about the verse. It says to be thankful "IN" all circumstances. It doesn't mean you have to be thankful for the circumstances, but it is a reminder that no matter what is going on, there is always something to give thanks for.
I'm thankful for so many things, but here are just a few:
My warm home
A career with flexibility so I can take care of Tom and still earn a living.
What are you thankful for today?
