3 Bible Verses about Deception, Satan's Power

The father whose sons you are is the Devil; and you desire to do what gives him pleasure. *He* was a murderer from the beginning, and does not stand firm in the truth--for there is no truth in him.

And when I was with you and my resources failed, there was no one to whom I became a burden--for the brethren when they came from Macedonia fully supplied my wants--and I kept myself from being in the least a burden to you, and will do so still. Christ knows that it is true when I say that I will not be stopped from boasting of this anywhere in Greece. And why? Because I do not love you? God knows that I do.

For men of this stamp are sham apostles, dishonest workmen, assuming the garb of Apostles of Christ. And no wonder. Satan, their master, can disguise himself as an angel of light.
