"Let your light so shine before men, that they may see your good works and glorify your Father in heaven." (Matt. 5:16)

I was cleaning out a desk drawer when I found a flashlight I hadn't used in over a year. I flipped the switch but wasn't surprised when it gave no light. I opened the flashlight and shook it to get the batteries out, but they wouldn't budge. Finally, after some effort, they came loose. What a mess! Battery acid had corroded the entire inside of the flashlight.

The batteries were new when I'd put them in, and I'd stored them in a safe, warm place, but there was one problem. Those batteries weren't made to be warm and comfortable. They were designed to be turned on, to be used. (From Ted Engstrom)

The same is true with us. The Christian is not designed to be warm, safe, and comfortable. He must be "turned on," letting his light shine, putting his love to work, diligently teaching God's word at every opportunity, and bearing up under persecutions and hardships.
