THE PAIN THAT WILL VANISH
The ability to sense physical pain can be beneficial. In fact, it is essential to human life. Hence, God’s promise that there will be no more pain could not mean that earthly subjects of Kingdom rule will become insensitive to all pain.
Rather, this promise that ‘pain will be no more’ indicates that mental, emotional and severe physical pain will vanish. Such pain has resulted from sin and imperfection. (Rom. 5:12; 8:21, 22) How will it ‘be no more’? In the sense that its causes will be eliminated.

‘No More Pain.’ Although unpleasant, the physical sensation of pain serves a beneficial purpose by alerting a person to danger regarding bodily damage and thereby enables him to take steps to avoid serious injury. The fulfillment of God’s promise that “neither will . . . pain be anymore” (Re 21:4), therefore, could not mean that humans would become insensitive to or incapable of experiencing pain. Rather, mental, emotional, and physical pain that has resulted from sin and imperfection (Ro 8:21, 22) will ‘be no more’ in the sense that its causes (such as disease and death) will be removed. That bodily perfection does not of itself require absolute painlessness is verified by the fact that even the perfect man Jesus experienced physical and emotional pain in connection with his death and the unresponsiveness of those to whom he ministered. (Mt 26:37; Lu 19:41) It was even foretold that he would be “a man meant for pains.” (Isa 53:3) By curing those “distressed with various diseases and torments” (Mt 4:24), Jesus bore the pains of others.—Isa 53:4.
