we know these are NOT TRIBULATION SAINTS,for the Spirit will not be here during that time,( only he who now let's will let until he be taken out of the way) 2 Thess.2:7
The Holy Spirit, being God, is omnipresent (everywhere present). It's a huge assumption to say the Holy Spirit ceases working during the GT.
We see many saved during the GT...mainly Jews...
(Rev 7:1) After this I saw four angels standing at the four corners of the earth, holding back the four winds of the earth, that no wind might blow on earth or sea or against any tree.
(Rev 7:2) Then I saw another angel ascending from the rising of the sun, with the seal of the living God, and he called with a loud voice to the four angels who had been given power to harm earth and sea,
(Rev 7:3) saying, “Do not harm the earth or the sea or the trees, until we have sealed the servants of our God on their foreheads.”
(Rev 7:4) And I heard the number of the sealed, 144,000, sealed from every tribe of the sons of Israel:
(Rev 7:5) 12,000 from the tribe of Judah were sealed, 12,000 from the tribe of Reuben, 12,000 from the tribe of Gad,
(Rev 7:6) 12,000 from the tribe of Asher, 12,000 from the tribe of Naphtali, 12,000 from the tribe of Manasseh,
(Rev 7:7) 12,000 from the tribe of Simeon, 12,000 from the tribe of Levi, 12,000 from the tribe of Issachar,
(Rev 7:8) 12,000 from the tribe of Zebulun, 12,000 from the tribe of Joseph, 12,000 from the tribe of Benjamin were sealed.
No one is saved apart from the work of God's Spirit.
If "only those who endured to the end" were saved apart from God's Spirit then salvation is by works/self effort.
