Abraham and Sarah

When The Lord told Abraham they would have a child, and Sarah laughed in the tent, then denied it to the angel, WMB said if it wasn't for Abraham, God would have struck her dead. The Bible never implies that whatsoever. In fact, the Lord never even rebuked her for it.

Also, Sarah's laughter was not disrespectful, but very typical, as was Abraham's.

Genesis 17:17 Abraham fell facedown; he laughed and said to himself, “Will a son be born to a man a hundred years old? Will Sarah bear a child at the age of ninety?”

After all, the Lord did tell them to call his name 'Isaac' which means 'laughter'.
