2 Thes.3 This chapter is dealing with the return of our LORD and Saviour Christ Jesus. The Apostle re-warns us, then addresses timing.
"Let no man deceive you." Spoken of first by Immanuel-Christ-Jesus(Matt.24:4). That day(the LORD'S Day) shall Not come, except there come a falling away(apostasy,Greek).
Apostasy = Greek: defection from the truth. Falling away. Forsake. Draw back. Figurative "offence," stumbling block.
Immanuel-Christ-Jesus spoke to HIS disciples in Matt.24:10 and employed the word "offended" = stumble. Is.8:15 many among them shall stumble, and fall, and be broken, snared, and be taken.
Remember: *two in the field, two grinding at the wheel, and two in the bed? One taken, the other one left: taken by Whom? The Antichrist-system now - and the Antichrist on the Sixth Trump.
2 Thes. 2:2-12 is about the Sixth Trump. Our LORD returns on the Seventh Trump.
"Neither cold, Nor hot" = Luke warm, shaky, double-minded, religious-folks, during these current times🕠🎺 are easily offended: especially concerning Truth.
The "Falling Away" stared with the leaders, in the early 1900s. The Unfederal-Reserves/International Redistribution of wealth Service, and It's 501c3 turned churches over to the State. "No inflation." It is hidden in plain sight 22,000000000000$. Those that have fallen, are also "blind."
