My son and I were trying to get my eight year old push-mower going (self-propelled, so I suppose “push” isn’t exactly right).
I had done a bit of work to it, so we took turns pulling the starter. It wore us both out. Then we remembered the starter fluid in the garage. One small squirt — it starts immediately!
It ran rough for a few minutes, then smoothed out comfortably.
My son suggested that starter fluid might be a good way to think of Jesus.
