This is one of the first scriptures I memorized as a new Christian, it helped that it was written on the wall of one the first churches we attended. Every Sunday I would read those verses and apply them to whatever confusing hard thing I might have been struggling with.
Age doesn't change everything, I still need the reminder that I will not always understand.
I must trust the Lord even when I don't understand, acknowledging that he is always good and always faithful. That he is in control of every situation and can use what I would understand as bad for his glory. I've seen it happen, it helps me believe for the future. That doesn't mean I don't have to go back to these verses and remind myself what is true, I still want to have it all figured out. He wants me to learn to trust, for me it will be a life long lesson.
