Yes, I believe that true Christians are not included in the word "all" as used in that verse.
The "somehow" is by, and through, Christ
So in your mind Christians can lie and be exempt from the warning given by the Lord which says...
But the cowardly, unbelieving, abominable, murderers, sexually immoral, sorcerers, idolaters, and all liars shall have their part in the lake which burns with fire and brimstone, which is the second death.”
So who do you believe the book of Revelation was written to?
