"Scare tactic"? Nope, just a fact. Why would you perceive that to be a "scare tactic"? 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"?
And "proof"?
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).
In a parable on the last judgment in Matthew 25:31, Jesus brought out this truth clearly. He concluded His parable saying, “These will go away into eternal punishment, but the righteous into eternal life” (v. 46).
Jesus said the most sobering thing about man’s eternal destiny. Hell is the destiny of those who refuse Him. Heaven is the destiny of those who believe in Him.
Jesus spoke of hell more often than did anyone else in the New Testament. He was not mean; He dealt with reality and truth. Nowhere in the Bible is there a hint of any possible reversal of the last judgment. There is no second chance after you die physically.
There is no escape from God’s judgment for eternity. The consequences of neglecting or rejecting God’s gift of life are tragic. It is plain from God’s Word that sin will be punished (Matt. 10:15; Dan. 12:2; Jn. 5:28-29; Rom. 5:12-21). No one will be exempt. The message of the Bible is clear that there is never any indication that the punishment of sin ever ceases.
The duration of the punishment will be the same as the gift of life. It is a never-ending “age to come.” Jesus said, “Then He will also say to those on His left, ‘Depart from Me, accursed ones, into the eternal fire which has been prepared for the devil and his angels” (Matt. 25:41). A little later He said, “These will go away into eternal punishment, but the righteous into eternal life” (v. 46). The apostle Paul gave the same emphasis when he wrote, “These will pay the penalty of eternal destruction, away from the presence of the Lord and from the glory of His power” (2 Thess. 1:9).
So my "proof" are the words of Christ. And it remains very, very sad and such a waste.
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.
