Piece by peace Jesus words become clearer and clearer.
"Also, there will be signs in sun and moon and stars, and on the earth anguish of nations, not knowing the way out because of the roaring of the sea and [its] agitation,  while men become faint out of fear and expectation of the things coming upon the inhabited earth; for the powers of the heavens will be shaken.  And then they will see the Son of man coming in a cloud with power and great glory.  But as these things start to occur, raise yourselves erect and lift YOUR heads up, because YOUR deliverance is getting near.” Lk21:24
Only Jehovah's king Jesus and his 1,000 year reign can heal the earth, and those chosen to participate.
