“"Free thinkers" are actually bondage thinkers because they are still trapped in their sin,”
Except I don’t accept the concept of sin. Meaning your claim here just sounds stupid.
"they are blind and refuse to admit they are locked in their own cages”
Yes, I disagree with your entire worldview. That’s pretty much inherent in being a freethinker. Are you confused about this? I could send you come brochures…
"but Jesus holds the key to eternal life for them; all they have to do is open their eyes and freely receive Jesus' salvation;”
Actually, long and careful thinking on Hell and sin is what opened my eyes. I would have to accept something i find offensive, which would be living a lie. And the Bible says God hates lying liars.
“only then can they become free in their thinking.”
Except this ‘freedom’ is confined to buying into someone else’s interpretation of a world-view. one that makes no sense.
