In my opinion, everyone should have a "life verse". A verse that they can go to when they need some guidance or encouragement or a course correction. I have several "life verses" (the Bible is a big book of a lot of books so it is hard to narrow to just one). If you don't have a life verse, try this one on for size. Walk around in it and see if it fits you.
Lord, life is hard and You never promised for it to be easy, but You have promised that I will get better at it through the hard times making me more capable and resilient.
