(2 Thessalonians 2:11 KJV) And for this cause God shall send them strong delusion, that they should believe a lie:
(Luke 8:10 KJV) And he said, Unto you it is given to know the mysteries of the kingdom of God: but to others in parables; that seeing they might not see, and hearing they might not understand.
(Matthew 11:25 KJV) At that time Jesus answered and said, I thank thee, O Father, Lord of heaven and earth, because thou hast hid these things from the wise and prudent, and hast revealed them unto babes.
2 Thessalonians 2:11 KJV) And for this cause God shall send them strong delusion, that they should believe a lie:
Nice try. Now go back and read the verse before and after and see what the "cause" is.
2 Thess. 2:10 (from the NKJV) ...and with all unreightousness deception among "those" (quotations mine) who perish, because "they" did not receive the truth, that "they" might be saved. 11: and for this reason God will send "them" strong delusion, that "they" should believe the lie, 12: that "they" all may be condemned who did not believe the truth but had pleasure in unrighteousness.
I said there has never been a time when God kept himself hidden from mankind nor allowed mankind to be deceived.This verse proves my point. It says they did not receive the love of truth, which means they were shown the love of truth, therefore God did hide himself from them. The "they" in this verse is "those who perish," those who "did not believe the truth", those who "had pleasure in unrighteousness", again showing that God did not hide himself from them but that they chose not to believe, again making my point. And the "they" these passages are referring to would hardly be considered all mankind.
the "you" in this verse is the disciples, he also in the previous verse says "He who has ears to hear, let them hear!" Again this verse proves that God does not hide himself from mankind.
because thou hast hid these things from the wise and prudent, and hast revealed them unto babes.
again hid from the wise, but not the babes.
