The bible tells us in 2 Thessalonians 2:11

11 And for this cause God shall send them strong delusion, that they should believe a lie:

When you are under the the "Great Delusion" it's very easy to not get it, to not "see it"

I know this because I, like all of you, were once there myself!
People have spoken about this brainwashing throughout history

Give me four years to teach the children and the seed I have sown will never be uprooted. - Vladimir Lenin

But is it really Satan that has deceived you?
Or have you allowed yourself to be deceived?

Man came with an "Owner's Manual,"
He has just been too pride filled to read it and follow the directions!

We get so full of "worldly knowledge" that we think we have a good handle on things! The problem with that is "Worldly Knowledge" is foolishness to Yahuwah! (Foolishness and LIES)

1 Corinthians
For the wisdom of this world is foolishness with God. For it is written, He taketh the wise in their own craftiness.

Ask Him to show you the Truth, and you'll find it!
Ask Him not, and you never will
