This one...
It's odd, I was far more dishonest when i was a uber dub bible believing "christian" than I am now as an atheist.
I find odd about myself too in that when I was an uber bible believing, praying to almighty God on a regular basis Christian I was more dishonest with people and living a double life. Of course, I was also single and in my 20s back then and now I am a married man in my 40s with two kids so that may also have something to do with it. I also never actually READ the Bible back then as much as I have now.
Noone really 'follows' the Bible as most just take the bits and pieces that they like and dismiss the rest as 'the old law.' For many of them, a habitual liar has a better shot at grace than a homosexual in spite of this verse:
Revelation 21:8
But the cowardly, the unbelieving, the vile, the murderers, the sexually immoral, those who practice magic arts, the idolaters and all liars--they will be consigned to the fiery lake of burning sulfur. This is the second death.
