Look at this translation for Matt 24:24-25 – “For false Christs shall arise, and false prophets, and will do wonderful miracles so that if it were possible, even God’s chosen ones would be deceived.”
Matt 24:24 [For false christs and false prophets will arise and perform great signs and wonders, so as to lead astray, if possible, even the elect. 25 See, I have told you beforehand.]
They are under a strong delusion of the lie that “Jehovah’s organization”, an idol, will lead them to salvation. (Rom 1:25) God allows this sifting of hearts, this choice of free will, just as was the case in the days of the Pharisees.
2 Thess 2: 10-12 you cited above says that those that believe the LIE did not love the truth that is why they will believe the LIE. What that means then is those that love truth won't believe the LIE.
I think it is safe to say that TRUE anointed love truth, therefore they would never believe the LIE/be deceived, so it will not be possible to lead them astray.
Also, the MOL has not come on scene yet, so the LIE/test has not been put forth yet. The MOL is the same as the wild beast/8th king, KOTN, disgusting thing, KFIC, etc.
9The coming of the lawless one will be accompanied by the working of Satan, with every kind of power, sign, and false wonder, 10and with every wicked deception directed against those who are perishing, because they refused the love of the truth that would have saved them. 11For this reason God will send them a powerful delusion so that they believe the lie, 12in order that judgment may come upon all who have disbelieved the truth and delighted in wickedness.
4They worshiped the dragon who had given authority to the beast, and they worshiped the beast, saying, “Who is like the beast, and who can wage war against it?13And the second beast performed great signs to cause even fire from heaven to come down to earth in the presence of the people. 14Because of the signs it was given to perform on behalf of the first beast, it deceived those who dwell on the earth, telling them to make an image to the beast that had been wounded by the sword and yet had lived.
20And the beast was captured, and with it the false prophet who in its presencee had done the signs by which he deceived those who had received the mark of the beast and those who worshiped its image. These two were thrown alive into the lake of fire that burns with sulfur.
