A curse to come

[may]

I have always wondered about this scripture.

I ask what curse could be greater than not receiving the love from both your parents?
What can you and I do to stop it?

And he must turn the heart of fathers back toward sons, and the heart of sons back toward fathers; in order that I may not come and actually strike the earth with a devoting [of it] to destruction."NWT......... ok, this is Jehovahs witness thoughts on the verse in malachi
through Malachi, God foretold: "Look! I am sending to you people Elijah the prophet before the coming of the great and fear-inspiring day of Jehovah. And he must turn the heart of fathers back toward sons, and the heart of sons back toward fathers; in order that I may not come and actually strike the earth with a devoting of it to destruction." (Malachi 4:5, 6) Elijah lived some 500 years before those words were uttered. Since this was a prophecy, Jews of the first century C.E. were in expectation of Elijah’s coming to fulfill it.—Matthew 17:10.
Who, then, was this coming Elijah? it was John the baptist,
John’s work got a prepared people ready for Jehovah.
It was in 70 C.E. that Jehovah fulfilled his Word by causing the Roman armies to execute divine judgment upon the nation that rejected his Son.
John 19:15.
However, there was more to come after 70 C.E. The apostle Paul associated a coming "day of Jehovah" with the presence of Jesus Christ. Moreover, the apostle Peter spoke of that day in connection with the yet future "new heavens and a new earth." (2 Thessalonians 2:1, 2; 2 Peter 3:10-13)
Bear in mind that John the Baptizer did an Elijahlike work before the "day of Jehovah" came in 70 C.E.
Elijah’s work not only had a parallel in the activities of John the Baptizer but also has one in those of anointed Christians in this critical period leading up to the coming "day of Jehovah." (2 Timothy 3:1-5) With Elijah’s spirit and power, they are staunch advocates of true worship
In his prophecy about his presence, Jesus outlined the globe-encircling work that would be completed before the end of this wicked system of things. (Matthew 24:14) Today, this work is being carried on by anointed Christians and their millions of companions who look forward to life on a paradise earth. Performing the Kingdom-preaching work until it is finished is a privilege granted only to those who are faithful like Elijah.
