Sadly, for some people laughter is the lost art, replaced with a self-pity that absorbs any attempts at humor. Experiencing loss, frustration, disappointment, and heartache, they say, "What's there to laugh at?" Life is an epic tragedy. But the beauty of the traditional tragedy is that it often ends with victory; the protagonist overcomes in the end, having endured great trials.
As Christians, we know that life ends with life! Death hold no sting and the grave has been conquered. In light of our eternal perspective, we can laugh, we can rejoice, we can find humor in life's upsets. Perhaps--just speculating here--that's why Jesus could laugh when others could not. After all, he/she isn't really dead, but merely sleeping.
Today, make every effort to hold onto an eternal perspective. We have overcome and these momentary troubles are but flickering shadows.
