Who of you by worrying can add a single hour to his life? (Matthew 6:27 NIV)
Sometimes, all I can do is work as hard as I can, hope for the best and be prepared for the worst because I have absolutely no control over the situation. I am thankful that in these situations I can trust in a God Who will always make things work for my best.

I am continuously struggling with this. I keep asking “but how do I know that there even is a God in control?”
I gave up trying to be in control a while ago. It was just too exhausting.
It really is.
