There is in fact more than one end of the world 2012 prediction for a 2012 earth "use by date". It has got to the point where the thought of a December 21 2012 dooms day is freaking some people out. Should you be freaked? We don't think so. For starters, given past doomsday predictions and prophecies about the end of the world, earth should have ended by now! Since the earth is still here, it would be fair to say then that, to date, all prophecies and predictions about the end of the world (before 2012) have failed!
WORD of CAUTION: Just because the earth has survived various doomsday predictions so far, doesn't guarantee it will still be here in the year 2012, or tomorrow for that matter? For tomorrow is not promised to anyone.
"It is appointed unto man once to die and then the judgement" (Hebrews 9:27). What if this was true? Would you gamble with your soul that these prophecies are not true? Consider the eternal consequences of being wrong. Imagine standing (if you were able to stand) before the creator of the universe, knowing that he is about to judge you.
What is more fearful than 2012 doomsday predictions?
Answer: Standing before God, without your sins forgiven.
"It is a fearful thing to fall into the hands of the living God." (Hebrews 10:31)
Answer: Being judged and found guilty by God.
“I say to you, My friends, do not be afraid of those who kill the body and after that have no more that they can do. But I will warn you whom to fear: fear the One who, after He has killed, has authority to cast into hell; yes, I tell you, fear Him!" (Luke12:4-5)
You are probably thinking, "I thought God was a God of love!" That's true, but he is also a God of justice and he has set aside a day of justice where the wicked will come before him
"Then shall he say also unto them on the left hand, Depart from me, ye cursed, into everlasting fire, prepared for the devil and his angels:" (Matthew 25:41)
