How do you allow yourself to be brainwashed?

How do you allow yourself to be brainwashed?
It is not a natural thing to do.
The answer is, you are first allured to a state of sleep. Then anything is programmable.
How do they do this?
They do this with bombs, misinformation bombs which overwhelm your normal thinking state.
In the pre mass communications days, people were much more free to have their own thoughts,  which developed over time and, together with your conscience made you the person you were.
This has been violated to such an extent in today’s world it has deaded this capacity and rendered the mind into a state of sleep, so that it can no longer analyse, filter and discern the information coming in from the outside, and this information is not truth. 
This cumulative programming, which is what it is, renders the person a slave of the controlling mindset and it is not a good mindset. If it were you would be lucky, but it is not.
Once you see for yourself this process you are free from it. They no longer have any control over you.
But if you sin they do. Sin dulls the senses and you are vulnerable once again.
The worst sins are sexual, sloth, gluttony,
and false pride.
Be vigilant. Say to yourself, you are not these things, one at a time. Call yourself by name first, and do it whenever temptation arises.
You can also add, do not steal and do not have an unhealthy envy of another person’s talents or goods. But I thought those would be obvious.
You need to withdraw yourself from sin now because we are in the last minute of the last days and the window will close on the mercy of God, before he comes to claim his own the rest are thrown into the fire. That’s how important and meaningful this life is, and you must treat it as such it perish. The life of God is life indeed. Why would you want to replace it with hell?
