3 Bible Verses about Deception, Satan's Power

"You are of your father, the devil, and you want to do what your father desires. He was a man-slayer from the very beginning; and he has no standing place in the truth, because truth is not in him. Whenever he utters a lie, he speaks from his nature, for he is a liar and the father of lying.

But I fear lest, just as the serpent beguiled Eve in his craftiness, so your minds should be seduced from your single-mindedness and purity toward Christ.

Yes, though I be unskilled in speech, at least I am not in knowledge; indeed I made this perfectly plain to you in all things and among all men. Is it a sin, forsooth, that I humbled myself that you might be exalted, in preaching the gospel to you free of cost? Other churches I spoiled, and took their wages to do you service. Even when I lacked the actual necessities of life while I was with you, I was a burden to no one; for whatever I lacked, the brothers from Macedonia supplied, when they came. 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, this boasting of mine shall not be stopped within the boundaries of Greece! And why? Because I love you not? God knows I do. I am doing and will continue to do this in order to cut away the ground from under those who wish some cause for slander; and that the ground of their boasting may appear as does mine. For such fellows are sham apostles of Christ. No wonder! for Satan himself disguises himself as an angel of light.

even he whose coming is according to the energy of Satan, in every power and sign and lying wonder, and with all deceit of unrighteousness for those who are perishing, because they did not receive the love of the truth for their salvation.
