What do you think leads people to be in such situations? Insanity, depravity? Why would anyone want to be deceived?
That is a good question. There are probably a myriad of paths that are taken.
But let's look at the enemies tactics with the temptation of Jesus.
He used;
Lust of the eyes - I will give you the kingdom of the worlds if you bow down and worship me
Lust of the flesh - turn these stones to bread
Pride of life - Throw yourself from the top of this temple and he will send his Holy Angles to grab you lest your foot dash a stone
I do not think he has changed his tactics one bit. Of course all his promises are lies unlike the promises of the Lord which are true and faithful.
If people stop and think for example about the prosperity gospel being preached. What is the core of that doctrine. Simple, greed, give 10% and extra and GOD will give you 30,60, 100 fold return. That is essentially fitting in to all three tactics that the devil used against Jesus if we stop and think.
Give money to get rich - Lust of the eyes, you can buy all you desire
Give money to get rich - Lust of the flesh, you can live an extravagant lifestyle, turning stone to bread so to speak.
Give money to get rich - Pride of life, you are testing GOD treating him like a slot machine and dumping money in expecting to hit a jackpot.
