Smile. It makes people wonder what you have been up to!
Many years ago I saw a card on a friend’s desk with that saying printed on it. I have never forgotten it.
The saying is true but it is also very sad. What has our world become that we are (almost universally) so cynical?
(Web definition of Cynical: 1. believing that people are motivated by self-interest; distrustful of human sincerity or integrity.)
What would our world be like if we smiled because we were truly happy?
1 Thessalonians 5.16 (MSG) Be cheerful no matter what; pray all the time; thank God no matter what happens. This is the way God wants you who belong to Christ Jesus to live.
