Bible Riddle

Rational irrationality; that’s what I call riddles, until I know the answer, and then it’s perfectly reasonable.

See if you feel the same way when you read this riddle, and then compare your feelings to when you figure out the answer:

I’m number three. But I’m not a number. I’m hot and cold at the same moment but not at the same time. Who or what am I?

To fulfill the Bible side of the riddle, check out Matthew 5:1-12 and look for the word that best fits as today’s answer.
