Readers -

The two part Resurrection & Rapture event in 1 Thess 4:16-17 actually begins with the Lord Himself Descending from Heaven...

this word Descending = Strong's 2597g,

gematria = 1185

note this verse

Matthew 24:37
"But as the days of Noe were, so shall also the coming of the Son of man be."

go here for a word by word breakdown found on the awesome Bible Wheel site:

note that the first word in Matthew 24:37 has a gematria value of

    1185

that is Strong's 5618g meaning "as, like, just as ..."

since it is the first word in the sentence it stands out.
