I walked a route that I use to walk when I was ten sizes smaller. I was nervous at first but after I started and after I finished I felt great.
Philippians 4:13
I can do all things through Christ which strengtheneth me.
I started walking today. I decided to walk to a store that was nearby. It was about a 30-45 minute walk there and back and I rewarded myself with a fruit juice that I drank on the way back home.
