My mom sent me this devotional about a wall of protection by email today, and I love it. You should totally read it here. I plucked this verse out of it as a good one for us to think about today! It spoke right to me.
We are pressed on every side by troubles, but we are not crushed. We are perplexed, but not driven to despair. We are hunted down, but never abandoned by God. We get knocked down, but we are not destroyed. – 2 Corinthians 4:8-9 (NLT)
