Your response works if you allow that "fear" is only "sin". You are suggesting that fear and sin are one and the same.
Sin - an immoral act considered to be a transgression against divine law.
Fear - an unpleasant emotion caused by the belief that someone or something is dangerous, likely to cause pain, or a threat.
I do not recognize "Divine" law on any level. Therefor I should have no fear and yet I do. Huh.
Only if you would recognise God, conform to the Bible, you would be free from fear. Not if you wouldn't. Therefore, you have fear, because you have no faith in God.
Fear and sin are not the same thing. It fits into your world because redefining words to mean other things when it suits your religion is the only way it has survived. God (the being that apparently created everything and is all powerful) would certainly be powerful enough to give humans words that remain true for all time. They would not have to e reinterpreted through the years to "Fit in" with the times. Gods words would be stronger that anything else in the universe your religion says he created. There would be no need to say, fear is sin and sin is fear and perhaps in another 2000 years, sin will have the added definition of being a bowl of chocolate chip cookies... Gods words, true for all time. Never having to be revisited or reinterpreted.

I do not reinterpret words. This is Christianity. Jesus commanded us never to fear.
To end, if you dont mind. Please tell me why Jesus called out to God and asked why he had been forsaken when he knew he was not?
He was. Jesus was bearing the sin of the world. God can not stand sin. So God turned away from His own son. That's what happened there on the cross.
