...Human beings are adept at rejecting objective evidence when it does not confirm their prejudice, no matter how clear or compelling the evidence may be. Some people will not be persuaded by all the proof in the world because they are not truly open to the evidence.
My experience as an apologist and minister has shown me that the real reason most people reject Christianity is not for lack of evidence. The proof from external sources regarding the truth of the biblical account is too overwhelming. No, the real issue is a moral one. The person not reconciled to God in Christ and living in disobedience does not want Scripture’s claim that God has a full and final claim on his life to be true...
R. C. Sproul as quoted @ inerrantword.org
and with all the deception of wickedness for those
who perish, because they did not receive the love
of the truth so as to be saved. For this reason God
will send upon them a deluding influence so that
they will believe what is false, in order that they
all may be judged who did not believe the truth,
but took pleasure in wickedness.
II Thessalonians 2:10-12
Yes, belief in the truth is a moral issue!
