I wonder if you are talking about Matthew 11:28, “Come to me, all you who are weary and burdened, and I will give you rest.” Regardless, I completely agree with everything you said!

Another verse that came to mind when I read your comment was, “Consider it pure joy, my brothers and sisters, whenever you face trials of many kinds, because you know that the testing of your faith produces perseverance.”—James 1:2-3

Our faith grows in our worst times.
