People who don't want to believe won't believe no matter what proof you show them, without faith you can not please God and God's people perish for the lack of knowledge. His knowledge is contained in the bible but those that won't read it won't find it. Those that read it and are not really looking for the truth won't find it. God knows your heart and mind and will only reveal His truth to those really looking for it for the right reason. If you read the bible trying to prove it wrong, you will not find the truth. If you are looking for flaws to diminish the faith of believers, your intent is evil and your eyes will be blinded to the truth. Just as the Jews were blinded to the truth that Jesus was their messiah, they would not accept Him, so the Gospel was taken to the Gentiles who did believe. Satan is the god of this world, the prince of the power of the air, but his reign is soon to be over. Man is given free will to choose to follow Satan or Jesus, and that choice will determine where you end up for eternity.

The bible requires believers to warn sinners that are heading for destruction, if we do not warn them and they die in their sins, their blood may be required of us, but if we warn them and they continue on to destruction, we will not be held responsible. We are also told not to cast our pearls before swine, if people are determine not to believe, we are wasting our time.
