WHAT EXACTLY IS IT THAT HAPPENS "IN THE TWINKLING OF AN EYE" ?

The Scripture states:

1 Corinthians 15:52

"In a moment, in the twinkling of an eye, AT the last trump: for the trumpet shall sound , and THE DEAD SHALL BE RAISED INCORRUPTIBLE, and WE SHALL BE CHANGED."

SO, THERE YOU HAVE IT:

The ONLY PART of the resurrection/rapture event that happens "in the twinkling of an eye" is the part where the dead in Christ are raised incorruptible and we who remain alive in Christ ARE CHANGED from mortal to immortal. The entire resurrection/rapture event , from beginning to end,  takes a little longer than "the twinkling of an eye." The entire resurrection/rapture event begins and ends according to:

1 Thessalonians 4:16 ( BEGINS )

"For the Lord Himself shall descend from heaven....  

1 Thessalonians 4:17 ( ENDS )

".............shall be caught up together with them IN THE CLOUDS to meet the Lord in the air...." ( these are THE SAME "CLOUDS OF HEAVEN" spoken of in Matthew 24:30 )

According to Your Holy Word, come Lord Jesus !
