I don't know how you arrived at your conclusion of"many are shocked"I was bought up by christians.
Reading the bible made me an atheist. I find most christians listen to the soundbites of the bible. When they actually read it cover to cover many are shocked.
When Iread the Bible cover to cover,I was inspired,tested many of it's teachings and was overcome with awe by the truths it contained
Let me give you an example;
When I read ;Romans 1:28-32
28 Furthermore, just as they did not think it worthwhile to retain the knowledge of God, so God gave them over to a depraved mind, so that they do what ought not to be done.
29 They have become filled with every kind of wickedness, evil, greed and depravity. They are full of envy, murder, strife, deceit and malice. They are gossips, 30 slanderers, God-haters, insolent, arrogant and boastful; they invent ways of doing evil; they disobey their parents; 31 they have no understanding, no fidelity, no love, no mercy. 32 Although they know Godís righteous decree that those who do such things deserve death, they not only continue to do these very things but also approve of those who practice them
When I read these verses,it was like looking in the mirror and I did not like what I saw.
What I read there,described the way I was,almost perfectly.
and I asked myself,Do you want to continue living your life this way,,The answer was no.
I was so impressed by what I read and the accurate description it gave of me,that I kept going back again and again to those verses.
I could not understand why these verses were having such a strong impact on me,a feeling that I could not describe,
I kept reading and eventually came to the Book of Hebrews,there I found the reason for the strong impact these verses were having on me,Now I could understand why I felt the way I did
Hebrews 4:12 ►
For the word of God is alive and active. Sharper than any double-edged sword, it penetrates even to dividing soul and spirit, joints and marrow; it judges the thoughts and attitudes of the heart.
