What would you do if someone who claimed to be your friend told terrible lies about you? Perhaps they did dishonest and cruel things to others, saying they were acting in your behalf. This person claimed you tortured your children when they misbehaved, or just did things you didn't like. How would you feel about this so-called "friend"?
I don't believe the Bible is open to private interpretations. Jesus said many would claim to serve him but he would say to them "‘I never knew you! Get away from me, you workers of lawlessness!’" (Matthew 7:23) Jesus also said: "Not everyone saying to me, ‘Lord, Lord,’ will enter into the Kingdom of the heavens, but only the one doing the will of my Father who is in the heavens will."
(Matthew 7:21) That is what I believe, since you asked.
So basically you are saying that accepting evolution is a ticket directly to Hell regardless an individual's other beliefs, lifestyle or relationship with Christ. Interesting...
So what does that mean for people who accept other interpretations in different areas of the Bible? Compare "once saved always saved" believers to "you can lose your salvation" believers. Only one of those doctrines is true so the other must be false. Does this mean that all individuals in the "wrong" group must necessarily go to Hell? How about people long ago who believed that Christian theology necessitated the Earth being at the center of the Universe with the Sun and stars orbiting it because humans were so important in the eyes of God? Today we know they were wrong. Are they in Hell now because they taught a non-truth? When it comes to Revelation, there are
many different interpretations. Come to think of it, there are probably no two people on Earth who share 100% of their interpretations of all verses in the Bible. Surely almost everyone has at least a few "wrong" interpretations. Does this mean that almost every Christian goes to Hell because they no doubt are wrong about some things?
For you friend analogy, there is a difference between intentionally spreading lies about someone and saying things about them that they genuinely believe are true. If I had an online friend who said that I was a female and
really believed that I was female, I would not have anywhere near as much of a problem with that as I would if they
knew that I was a male and told others that I was a female for some malicious purpose. Very difference scenarios.
As far as "private" interpretation goes, there is a major problem with that. All denominations believe that
their interpretation is God's truth and that all others are private interpretations based on fallible human reasoning. Who is right? I believe that one's relationship with Jesus Christ and following His commandments are of significantly greater importance than getting hung up on how different groups of Christians interpret the historicity of the Bible.
Just because I accept evolution doesn't mean that I reject the concept of sin. Nor does evolution necessarily preclude the existence of Adam and Eve. They may have been the first hominids capable of fully understanding right from wrong, or they may have been the first hominids to whom God revealed Himself, or any number of other possibilities. At any rate, I do believe that the creation account in Genesis is true but in a metaphorical or at least somewhat-less-than-literal sense. So I still believe in the infallibility of the Bible, even if my interpretation of the Bible's truth doesn't match up with yours.
