To accept that Jesus Christ was the Messiah and that he rose from the dead would mean quite a lot. Like, you would have to bow the knee/change your life. I don't think people want to do that. It's much nicer to believe that no one is in charge of your life except you.
I've studied the evidence and I'm convinced that Jesus rose from the dead. It's not like I'm a brainwashed zombie. I know that it sounds absurd to seriously give credit to a story about a man rising from the dead. At one point, I thought it was rubbish, too! I know it sounds weird to abstain from all sorts of 'normal' things, or to sit around and pray. I used to think it was totally stupid to waste your time at church on a Sunday morning. After all, you could be sleeping in.
Something in me told me that if hell were a real place, and people I knew thought I was going there, regardless of my ignorance, I should at least check it out thoroughly. I mean, what if I were wrong? I'd be in hell. That would really suck to say "I decided I didn't like the idea of hell, so I chose to have it not be real for me. Unfortunately, this truth was not relative."
Imagine being on the Titanic, and being told by your friend that the ship was sinking. You could laugh and say that the Titanic wasn't sinking. You could rationalize the situation in your mind, given the knowledge that you have. Regardless of what you knew, though, if you didn't go out of your cabin just to make sure, you'd be pretty stupid.
People have reasons for not believing in Jesus, but I really don't think that its all about science or truth. It's about having to change your life, and that isn't always appealing.
Most of the people I know don't make Jesus their king because of something other than facts. They don't want to change their life, or have to go to church, or have to admit they're wrong on some things.
This is just an internet forum, though. I'm only posting my opinion. These words, I'm almost sure, will never cause a conversion or anything. Just throwing out thoughts.
And... I love you all. No hard feelings.
