Good you see the 144k as being Jewish that is very good, yet they do indeed have work to do, they are those who sperad the gospel druing the great tribulation as well as the two witnesses. Sadly no one is raptured once the great tribulation gets going. It is by way of the ministry of the 144k (and the two witnesses)
all Israel is saved in the great tribulation.
Rom11:25For (
AL)I do not want you, brethren, to be uninformed of this (
AM)mystery--so that you will not be (
AN)wise in your own estimation--that a partial (
AO)hardening has happened to Israel until the (
AP)fullness of the Gentiles has come in;
26
and so all Israel will be saved; just as it is written,
"(
AQ)THE DELIVERER WILL COME FROM ZION,
HE WILL REMOVE UNGODLINESS FROM JACOB."
27"(
AR)THIS IS MY COVENANT WITH THEM,
(
AS)WHEN I TAKE AWAY THEIR SINS."
But don't get the idea that they will be saved as a result of them being Jews... no one is saved by way of thier heritage, they will be saved by faith like each and every other perosn who is saved was. By faith appart from works.
