Immanuel explanation(Mat12:40) of Jonah, 3 Days in the belly of a great fish, would take HIM 3 Days in the earth, just as Jonah - is extremely-significant.
3 Days and 3 Nights, dead: then Resurrection. This is Prophecy, as well as a huge Sign. Many of the House (12 Tribes) were awaiting the Messiah, and would recognize this Sign.
Other Religious folk who were always seeking after Miracles, would hopefully become Believers.
Jonah(1:17) "was swollen up by a great fish that the LORD had prepared." Dead: 3 Days and 3 Nights. "Out of the belly of hell I cried out"(J.2:2).
It is imperative that Witnesses understand that Our LORD, and Jonah, we're physically - dead.
Apostle John (2Jn.1:7) calls "deniers, Antichrist."
Who in 2018 would this be? Religion!×6
To stand on Christ Crucifixion on Friday, and Resurrected on Sunday, is denying Immanuel-Christ-Jesus purpose for coming in the flesh.
To stand as a denier, is standing on sand. The great fish was prepared for Jonah, by the same ONE that spent 3 days and nights in the (tomb): same hell as Jonah.
It is HE, that has the stop-watch of Life, and has a place prepared for us - Good, or bad.
