Satan's schemes are powerful, so yes, obviously people are being sucked in and have no idea what is happening. But the elect will be saved. The bible is clear that God protects the elect, that they cannot be snatched out of his hand. Jesus said he will not lose one that the Father has given him. But I do very much believe even the elect can be deceived for a time, hence the scriptures that talk about the lost sheep, etc.
Matthew 24:24
For false christs and false prophets will arise and perform great signs and wonders, so as to lead astray, if possible, even the elect.
John 6:39
And this is the will of him who sent me, that I should lose nothing of all that he has given me, but raise it up on the last day.
