As Finklestein points out above, the Bible does indeed Contradict itself.
Jesus too contradicted himself, he came to Fulfill the Law, and perfectly expound it, he says in Matthew 5:17 "Do not think that I have come to abolish the Law or the Prophets; I have not come to abolish them but to fulfill them." But contradictory to this statement he says - "So Jesus said to them, “Truly, truly, I say to you, unless you eat the flesh of the Son of Man and drink his blood, you have no life in you." - John 6:53 This statement clearly contradicted the Portion of the Law at Deut 12:16 that forbids the eating or drinking of Blood.
Those listening were Confused, and some were disgusted. As Tigersuit brings out above reading the bible, leads many to becoming atheist.. Likewise Jesus contradictory statements, lead many to reject the Messiah.
The issue lies in people viewing the Bible as God.
They reason.. God is supposed to be infallible, and the Bible is his Direct Word.. If the bible is found to be fallible, God is fallible, and from this they extrapolate the belief that God does not exist. Their expectatiOn of God is correct, God is a God of love and Infallible, but their viewpoint of the Bible is Flawed.
Jesus understood this reasoning, and he said "You are in error because you do not know the Scriptures or the power of God." Matthew 22:29 - What he meant about not understanding the scriptures is seen at Hebrews 4:12 " For the word of God is living and active, sharper than any two-edged sword, piercing to the division of soul and of spirit, of joints and of marrow, and discerning the thoughts and intentions of the heart."
God did not provide the Bible exclusively so that we could Learn who he is, and test him.. God provided Humanity the Bible so that we could be Tested by it.
Unless an Individual is Humble and Deaires to be Righteous, he/she finds what ever they wish in the Scriptures.
- If they have evil desires, they find Justification For evil.
- If they wish to commit fornication and adultery they find justification in the Bible.
- If they wish to follow their own Law as opposed to God's they find Contradictions in the Bible, that allow them to Beleive that God does not exist.
- If they seek to be righteous they find the Way To Life in the Bible.
