False Saving and Teachers

I have heard many times that being saved and Baptized, along with belief that Jesus is the Son Of God is all it takes. I don't agree with that personally for even the Devil knows who Jesus is and accepts that fact. The Devil (Satan) can and I'm sure does even profess that he follows Him with his words yet his actions are in the opposite direction. That would be easily spotted if it were all bad actions, but it's not. 90% truth and 10% lie can easily drop the smartest of men.

  John 325. There arose a question between one of the disciples of John and a
Jew over [ceremonial] washing.
26. And they came to John and said to him, "Rabbi, the one who was
with you at the crossing of the Jordan [river,] of whom you testified,
behold, he is also baptizing and many are coming to him."
27. John replied and said to them, "No human [being] can of his own will
[receive] anything, unless it comes to him from heaven.
28. "You are my witnesses that I said, 'I am not the Anointed One,
except the apostle before him.'
