“Sarah said, ‘God has brought me laughter, and everyone who hears about this will laugh with me’" (Genesis 21:6).
This is Sarah's statement after God blessed her and her husband Abraham with a son. Sarah was 90 years old and Abraham was 100.
Any passages in the Bible that hints at a sense of humor?
"A merry heart doeth good like a medicine" Proverbs 17:22
By Aristotle’s rule of thumb, God’s plan for the ages is a comedy, because no matter how tragic this world may seem, it ends with a wedding (Rev 19:6–10).
