Anyway, thinking of laughter, on the way home I was thinking about stuff and on came this song that's often playing on 103.2 - One Step at a Time. I reckon God has a sense of humour - after all He was the one who created laughter.
I was looking up laughter on Bible Gateway to find the Proverb that mentions it being like medicine, and came across these verses in Genesis 21:
5 Abraham was a hundred years old when his son Isaac was born to him.
6 Sarah said, "God has brought me laughter, and everyone who hears about this will laugh with me." 7 And she added, "Who would have said to Abraham that Sarah would nurse children? Yet I have borne him a son in his old age."
Just thought it was interesting that she used the word laughter. I also realised the verse I was thinking of actually says a cheerful heart is good medicine (Proverbs 17:22). Oh well. Still think laughter is good.
