I have a couple favorites that I've always remembered. I can never quote them exactly, nor could I tell you book, chapter, and verse, so I looked them up.
One has to do with equality. As I've grown into an adult, it's always been in the back of my mind as a kind of measuring stick for how I treat others and how people in general act toward each other.
Galatians 3:28 ESV
There is neither Jew nor Greek, there is neither slave nor free, there is no male and female, for you are all one in Christ Jesus.To me, this means that we are all equal in the eyes of God. No one is more deserving of mercy, and no one is less deserving. On any level.
The other one is a verse that a family friend quoted to me many years ago. I used to have a near-debilitating fear of the dark, even into my teens. I could not bear to be in a totally dark room, or go outside without a light after dark. Not alone, anyway. If someone was with me I was fine. After she told me about this verse, though, I used to say it to myself repeatedly whenever I had to go outside at night. And it helped. In fact, I am pretty sure it's what cured me of that fear. (Although living in town now where we have street lights at night isn't bad either.)
