4 Bible Verses about Deception, Satan's Power

You are of your father the devil, and it is your will to practice the desires [which are characteristic] of your father. He was a murderer from the beginning, and does not stand in the truth because there is no truth in him. When he lies, he speaks what is natural to him, for he is a liar and the father of lies and half-truths.

Now the serpent was more crafty (subtle, skilled in deceit) than any living creature of the field which the Lord God had made. And the serpent (Satan) said to the woman, “Can it really be that God has said, ‘You shall not eat from any tree of the garden’?” And the woman said to the serpent, “We may eat fruit from the trees of the garden, except the fruit from the tree which is in the middle of the garden. God said, ‘You shall not eat from it nor touch it, otherwise you will die.’” read more.
But the serpent said to the woman, “You certainly will not die!

But I am afraid that, even as the serpent beguiled Eve by his cunning, your minds may be corrupted and led away from the simplicity of [your sincere and] pure devotion to Christ. For [you seem willing to allow it] if one comes and preaches another Jesus whom we have not preached, or if you receive a different spirit from the one you received, or a different gospel from the one you accepted. You tolerate all this beautifully [welcoming the deception]. Yet I consider myself in no way inferior to the [so-called] super-apostles. read more.
But even if I am unskilled in speaking, yet I am not [untrained] in knowledge [I know what I am talking about]; but we have made this evident to you in every way, in all things. Or did I [perhaps] sin by humbling myself so that you might be exalted and honored, because I preached God’s gospel to you free of charge? I robbed other churches by accepting [more than their share of] financial support for my ministry to you. And when I was with you and ran short [financially], I did not burden any of you; for what I needed was fully supplied by the brothers (Silas and Timothy) who came from Macedonia (the church at Philippi). So I kept myself from being a burden to you in any way, and will continue to do so. As the truth of Christ is in me, my boast [of independence] will not be silenced in the regions of Achaia (southern Greece). Why? Because I do not love you [or wish you well, or have regard for your welfare]? God knows [that I do]! But what I am doing I will keep doing, [for I am determined to keep this independence] in order to cut off the claim of those who want an opportunity to be regarded just as we are in the things they brag about. For such men are counterfeit apostles, deceitful workers, masquerading as apostles of Christ. And no wonder, since Satan himself masquerades as an angel of light.

The coming of the [Antichrist, the lawless] one is through the activity of Satan, [attended] with great power [all kinds of counterfeit miracles] and [deceptive] signs and false wonders [all of them lies], and by unlimited seduction to evil and with all the deception of wickedness for those who are perishing, because they did not welcome the love of the truth [of the gospel] so as to be saved [they were spiritually blind, and rejected the truth that would have saved them].
