Researchers have concluded that there are costs associated with self-deception:

The invisible downside of cheating in life
People who take shortcuts can trick themselves into believing they are smarter than they are, says Tom Stafford, and it comes back to bite them. …
The researchers ran another experiment to check that the effect was really due to the cheaters’ inflated belief in their own abilities. In this experiment, students were offered a cash reward for accurately predicting their scores on the second test. Sure enough, those who had been given the opportunity to cheat overestimated their ability and lost out – earning 20% less than the other students.
The implication is that people in Chance’s experiment – people very much like you and me – had tricked themselves into believing they were smarter than they were. There may be benefits from doing this – confidence, satisfaction, or more easily gaining the trust of others – but there are also certainly disadvantages. Whenever circumstances change and you need to accurately predict how well you’ll do, it can cost to believe you’re better than you are.
That self-deception has its costs has some interesting implications. Morally, most of us would say that self-deception is wrong. But aside from whether self-deception is undesirable, we should expect it to be present in all of us to some degree (because of the benefits), but to be limited as well (because of the costs).
Self-deception isn’t something that is always better in larger doses – there must be an amount of it for which the benefits outweigh the costs, most of the time. We’re probably all self-deceiving to some degree. The irony being, because it is self-deception, we can’t know how often. http://www.bbc.com/future/story/20150225-unexpected-downside-for-cheaters

Jesus taught that Satan was a liar and the father of lies:

44 You are of your father the devil, and the desires of your father you want to do. He was a murderer from the beginning, and does not stand in the truth, because there is no truth in him. When he speaks a lie, he speaks from his own resources, for he is a liar and the father of it (John 8:44)

Of course, Satan takes advantage of deception and encourages humans to deceive themselves. Recall what happened to Eve:

14 And Adam was not deceived, but the woman being deceived, fell into transgression. (1 Timothy 2:14)
6 So when the woman saw that the tree was good for food, that it was pleasant to the eyes, and a tree desirable to make one wise, she took of its fruit and ate. She also gave to her husband with her, and he ate. (Genesis 3:6-7)

Satan was involved, but the woman allowed herself to be deceived. This type of deception happens every day.

But what about Christians? Can Christians fall victim to self-deception?

Jesus warned that most Christians in the end times would be deceived:

14 “And to the angel of the church of the Laodiceans write,
‘These things says the Amen, the Faithful and True Witness, the Beginning of the creation of God: 15 “I know your works, that you are neither cold nor hot. I could wish you were cold or hot. 16 So then, because you are lukewarm, and neither cold nor hot, I will vomit you out of My mouth. 17 Because you say, ‘I am rich, have become wealthy, and have need of nothing’ — and do not know that you are wretched, miserable, poor, blind, and naked — 18 I counsel you to buy from Me gold refined in the fire, that you may be rich; and white garments, that you may be clothed, that the shame of your nakedness may not be revealed; and anoint your eyes with eye salve, that you may see. 19 As many as I love, I rebuke and chasten. Therefore be zealous and repent. (Revelation 3:14-19)

Although most Laodiceans do not believe that they are deceiving themselves, Jesus said that they are. Jesus said that Laodicean Christians need to repent–they need to change. They should not let pride get in their way.

The Continuing Church of God (CCOG) put out the following video on our Bible News Prophecy YouTube channel:

Pride: Quit Lying to Yourself
‘The Atlantic’ ran an article titled “Quit Lying to Yourself.’ It explained that this was not good and does not lead to happiness. The BBC ran an article about dangers of self-deception. The Bible warns about lies, self-deception, and pride. Does the New Testament warn that Christians can be deceived? What did Jesus say was the truth? What did Jesus tell end-time Laodicean Christians to do? Dr. Thiel addresses these issues and more in this video.

Here is a link to the sermonette video: Pride: Quit Lying to Yourself.

In addition to doctrine and how they lead their lives, there are serious prophetic deceptions that the Laodiceans have fallen for. A list of 50+ prophetic deceptions that various Laodiceans (and those of Sardis) believe is in the article The Laodicean Church Era. Believing several of these will ensure that Laodiceans will not realize that the Great Tribulation is here until it is to late for most to flee (cf. Revelation 12:14-17).

Self-deception is common. Try not to fall for it. The word of God is truth (John 17:17), hopefully you will believe it enough so that you will resist Satanically-encouraged self-deception (cf. James 4:7).

And, with the US midterm elections coming up, do not deceive yourselves about them either–pray for leaders (1 Timothy 2:1-3) and that God’s will will be done (Acts 21:14; Matthew 6:10).
