My response is not directed at you
JLB, but rather the common belief that you and many hold to concerning the scripture you quoted.
You will never understand the scripture as you should as long as you hold fast to the idea of a singular Anti-Christ devil character you are waiting to see destroyed to fulfill some sort of prophesy according to your flesh.
But it takes courage, humility and Faith to recognize and accept that it is you who is the man of sin that the scripture speaks of. It is you who is a son of perdition, or rather a son that goes into perdition. Living after the flesh and your understanding thereof, forever trying to perfect your own flesh as an acceptable sacrifice before the Lord.
I am a man of sin, you are a man of sin, each of us is a man of sin after the nature of our flesh. If this was not so, then there would be no reason for you to need a savior in the first place, would there? But as the scripture says of the man of sin, the Lord shall consume him with the SPIRIT of his mouth. By Faith, our old nature is consumed in Christ. By Faith we have been baptized into the death of Christ. Knowing that our old man is crucified with him that the body of sin might be destroyed. (Romans 6:3-6)
God is a Spirit, and must be worshipped in spirit and in truth. The Spirit of Christ has made his abode in the hearts of man, and he instructs us by his Spirit, as we are created in his image. So when one is destroyed by the Spirit of his voice, how shall I imagine what that might look like?
1 Corinthians 2:9-14
But as it is written, Eye hath not seen, nor ear heard, neither have entered into the heart of man, the things which God hath prepared for them that love him. But God hath revealed them unto us by his Spirit:for the Spirit searcheth all things, yea, the deep things of God. For what man knoweth the things of a man, save the spirit of man which is in him? even so the things of God knoweth no man, but the Spirit of God. Now we have received, not the spirit of the world, but the spirit which is of God; that we might know the things that are freely given to us of God.
Which things also we speak, not in the words which man's wisdom teacheth, but which the Holy Ghost teacheth; comparing spiritual things with spiritual. But the natural man receiveth not the things of the Spirit of God: for they are foolishness unto him: neither can he know them, because they are spiritually discerned.
Matthew 13:13-14
Therefore speak I to them in parables: because they seeing see not; and hearing they hear not, neither do they understand. And in them is fulfilled the prophecy of Esaias, which saith, By hearing ye shall hear, and shall not understand; and seeing ye shall see, and shall not perceive.
Jesus said in many places, he who hath an ear to hear, hear what the spirit saith unto you.
