If while hiking or playing you developed a blister, you probably would not notice it until it became a terribly ulcerated sore. Also, it would be dangerous for you to attend a barbecue, or be anywhere near a fire, for a spark could badly burn you before anyone noticed it. Being unable to feel pain can have serious, even disastrous consequences.

Yes, indeed, pain is an important warning signal of the body. It, in effect, forces you to take action to protect yourself.

PAIN is something of a paradox. It can constitute a dreaded affliction. Or it can serve as a real protection.

The sensation of pain causes us immediately to draw our hand away from an object that is so hot it would damage our flesh. This sensation of pain​—this marvelous warning mechanism of the body—​is not what the Bible is speaking about when it promises that “neither will . . . pain be anymore.”​—Rev. 21:4.
