A fact?
If I tell a 16 year old that if they drink and drive and a cop pulls them over they will lose their drivers license, is that a fact or a "scare tactic"?
That's apples and oranges. We don't have to "believe" that cops exist and what they might do. You are confusing faith with facts.
Jesus Christ made it very clear that a person’s relationship with God in this present life will determine his destiny in the life to come (Matthew 19:16-26; 7:13-23).
No, the Bible says that, and you choose to believe the Bible. Just because you believe it idoesn't mean it's true. Muislims believe the Koran is true, and Jews reject the NT and believe only the OT is true. It's a matter of faith, not fact.
We'll all find out one way or another one of these days if there really is a price to be paid for rejecting Christ.
And that is a fact, by anybody's definition.
