The Bible does not say the saints will not see the day of wrath. Paul writes in I Thessalonians ...ye are not appointed unto wrath, but to obtain salvation through our Lord Jesus Christ.
Paul's TWO Thessalonians epistles are in the context of an "
eschatological salvation" (not like the eternal salvation / justification / soul-saving, etc type thing); so in the sense of being "delivered" (from adverse circumstances, or the like), just as 1Th1:10 is saying.
--"[put on]... and for an helmet,
the HOPE of salvation" [which speaks of "our Rapture" event and our bodily glorification / perfection occurring at that time]
--"but to obtain salvation" (an
eschatological salvation)
Do you believe the saints that come out of the great tribulation, who overcome by the blood of the Lamb and the word of their testimony are appointed unto wrath instead of to obtain salvation through our Lord Jesus Christ?
First of all, this text is governed by the "you" (that's who--referring to and addressed to "the Church which is His body"--ALL those having come to faith "in this present age [singular]"... and just like how Paul in v.10's "that WHETHER WE MAY WATCH or WHETHER WE MAY SLEEP" is distinct from that which Jesus was saying [re: WATCH or else!]);
We already know from the OT that "saints" (thus are "saved" persons in that sense) will exist during the time period we now know as the tribulation period and the GREAT tribulation, of whom Scripture itself had said of them, "I beheld, and the same horn made war
with the saints and PREVAILED AGAINST THEM" (corresponding with Revelation 13:5,7, yet future); but we see that Jesus said something specific in Matthew 16:18, "And I also say to you that you are Peter, and on this rock
I will build My church, and
the gates of Hades
not will prevail against it."
Where 1Th1:10 says, "the
One delivering US out-from THE WRATH COMING," it is saying "us" (the Church which is His body); it is not saying that there will exist no "saints" (having come to faith IN / DURING / WITHIN the Trib yrs) nor that they will be taken out prior to "the wrath coming" (and again, it is not specifying ONLY GOD's wrath, here, it just speaks of "THE WRATH COMING," tho yes, God's wrath can be seen as early as the "2nd Seal WARS" if one compares Scripture with Scripture and considers that Ezek38:18-19's "WRATH" words pertain as PART of those "wars").
So, sure there will be "saints" who come to faith WITHIN that time period; but the text in 1Th5:8-9 ("not appointed US to wrath, but to obtain salvation [
eschatological 'salvation' i.e. being physically delivered out-of certain circumstances that will exist upon the earth]) is specifically addressed pertaining to (to / for / about) "US" (not to all other "saints" of all other time periods, i.e. Trib saints--this passage is not addressed
to them);
and recall (lest you consequently think "wrath" would then be DIRECTED TOWARD them, as "saints" [which I'm not suggesting]), that in the "70ad events" section of the Olivet Discourse (past events, from our perspective), it says, "and WRATH upon this people" Luke 21:23,20 (see also Matt22:7, speaking of that same set of events, back in 70ad and surrounding, "But when the king heard thereof, he was WROTH: and he sent forth his armies, and destroyed those murderers, and BURNED UP THEIR CITY"--corresponding also with Jesus' words in Lk19:41-44 spoken on what we call Palm Sunday, the precise day of the conclusion of the 69 Weeks--that the "70 Weeks prophecy" pertaining also to "Jerusalem / the city / "are determined upon... thy [Daniel's] holy city" );
Now, to be clear, I'm not saying that 1Th1:10's "the wrath coming" WAS those 70ad events, just that there was His "wrath" then as well. And again, the text in 1Th1:10 does not specify WHOSE wrath (so Satan's wrath can ALSO be INCLUDED in this, see... not that that makes any significant difference, it's just something you hear people saying all the time...)
