Public Service Announcement:
If all a person wants to do is "share their opinions" and leave it at that, nothing wrong with that. But if you are going to say "the Bible truth is XYZ", you need to be able to defend your claims. Otherwise, you're just being foolish.
State your claim, then SHOW FROM THE BIBLE how the Bible says what you are saying and means what you are meaning.
Then be prepared for questions. People will say "If what you are saying is true, then ABC naturally follows as a consequence." Don't get upset, this is how humans interact, learn, and discuss, and debate. If ABC is NOT correct, you need to SHOW HOW and WHY. It's nothing personal, it's not a personal attack. It's a conclusion drawn from your statements. If it's incorrect, then show how it is incorrect, and why.
If someone makes their case, and you disagree, EXPLAIN HOW THEY ARE WRONG. Don't just make the statement, rather take what they said, refer to the Scriptures, and PROVE how the other side is wrong. And expect questions.
Proof, refutation, counterproof. That's how it works.
