19 You believe that God is one. You do well; the demons also believe, and shudder. - James 2
Calling ones self a believer in Christ does not make one a follower of Christ, as the above scripture points out.
The Devil knows scripture. He preaches. His doctrine is chocked full of bible verses... and its all lies built on the counterfeit in order to set himself up like God.
And we so often believe every word because it is darkness, but brightly lit.
The enemy wants to be Jesus. The enemy has spirits. The enemy can perform works, and signs and wonders...
BUT IT IS STILL A LIE THAT DOES NOT CONFORM TO THE WORDS OF GOD.
Then Jesus was led up by the Spirit into the wilderness to be tempted by the devil. 2 And after He had fasted forty days and forty nights, He then became hungry. 3 And the tempter came and said to Him, “If You are the Son of God, command that these stones become bread.” 4 But He answered and said, “It is written, ‘Man shall not live on bread alone, but on every word that proceeds out of the mouth of God.’”
5 Then the devil *took Him into the holy city and had Him stand on the pinnacle of the temple, 6 and *said to Him, “If You are the Son of God, throw Yourself down; for it is written,
‘He will command His angels concerning You’;
‘On their hands they will bear You up,
So that You will not strike Your foot against a stone.’”
7 Jesus said to him, “On the other hand, it is written, ‘You shall not put the Lord your God to the test.’”
4 But the Spirit explicitly says that in later times some will fall away from the faith, paying attention to deceitful spirits and doctrines of demons, 2 by means of the hypocrisy of liars seared in their own conscience as with a branding iron- 1 Tim 4
3 Let no one in any way deceive you, for it will not come unless the apostasy comes first, and the man of lawlessness is revealed, the son of destruction, 4 who opposes and exalts himself above every so-called god or object of worship, so that he takes his seat in the temple of God, displaying himself as being God. 5 Do you not remember that while I was still with you, I was telling you these things? 6 And you know what restrains him now, so that in his time he will be revealed. 7 For the mystery of lawlessness is already at work; only he who now restrains will do so until he is taken out of the way. 8 Then that lawless one will be revealed whom the Lord will slay with the breath of His mouth and bring to an end by the appearance of His coming; 9 that is, the one whose coming is in accord with the activity of Satan, with all power and signs and false wonders, 10 and with all the deception of wickedness for those who perish, because they did not receive the love of the truth so as to be saved. 11 For this reason God will send upon them a deluding influence so that they will believe what is false, 12 in order that they all may be judged who did not believe the truth, but took pleasure in wickedness.- 2 thes 2
43 Why do you not understand what I am saying? It is because you cannot hear My word. 44 You are of your father the devil, and you want to do the desires of your father. He was a murderer from the beginning, and does not stand in the truth because there is no truth in him. Whenever he speaks a lie, he speaks from his own nature, for he is a liar and the father of lies. 45 But because I speak the truth, you do not believe Me.- John 8
4 Hear, my children, the instruction of a father,
And give attention to know understanding;
2 For I give you good doctrine:
Do not forsake my law.- Proverbs 1-2
What is the doctrine of the adversary? Lies and lawlessness.
What is the truth and good doctrine? Faith resulting in obedience.
