I guess thats the question.... can the elect (not elite) actually be led astray? I don't think so...
Barnes notes on the NT says "So nearly would their pretended miracles resemble true miracles as to render it difficult to detect the imposture; so much so, that if it were possible they would persuade even true Christians that they were the Messiah. But that was not possible."
Robertson's Word Pictures says "Teras is a wonder or prodigy, dunamis, a mighty work or power, sēmeion, a sign of God’s purpose. Miracle (miraculum) presents only the notion of wonder or portent. The same deed can be looked at from these different angles. But the point to note here is that mere “signs and wonders” do not of themselves prove the power of God. These charlatans will be so skilful that they will, if possible (ei dunaton), lead astray the very elect. The implication is that it is not possible."
Calvin said "For they have not sufficient energy to resist the attacks of Satan, unless in consequence of their being the sheep of Christ, which none can pluck out of his hand, (Joh_10:28.)
It must therefore be observed, that the permanency of our salvation does not depend on us, but on the secret election of God; for though our salvation is kept through faith, as Peter tells us, (1Pe_1:5,) yet we ought to ascend higher, and assure ourselves that we are in safety, because the Father hath given us to the Son, and the Son himself declares, that none who have been given to him shall perish (Joh_17:12.)."
one more... Gill said "By whom we are to understand, not the choicest believers, or the persevering Christians: not but that such who are truly converted, are choice believers in Christ, and persevering Christians are undoubtedly the elect of God; but then the reason why they are elect, and why they are so called, is not because they are converted, are choice believers, and persevering Christians; but, on the contrary, the reason why they are converted, become true believers, and persevere to the end, is, because they are elected; conversion, faith, and perseverance being not the causes or conditions, but the fruits and effects of election: besides to talk of the final seduction of a persevering Christian, is a contradiction in terms. Such an interpretation of the phrase must be absurd and impertinent; for who knows not that a persevering Christian cannot be finally and totally deceived?"
