is judgement day true or false?

I believe that judgment day is true. I believe in God and the time that He will judge us all for the things we have done. He is giving us a lifetime to know Him through His Son. God rewards us by the things we do. He will reward everything good we have done. But He is just that He will also punish everything bad we have done. All the rewards are given during our lifetime. One thing I really believe in (based from the Bible of course) during the last days is that the final judgment will be given. It is either we are eternally separated from God (casted to Hell) or will have our eternal life with Him. And this decision is based on our belief with Christ. I thank God for giving me the time to know Him and know that I have eternal life through Christ.

Everything that starts have to end in some way, so the judgement day is a fact. Question is... does it going to be mistical judgement day or we will be just all killed in few seconds? I think that it will be something between these two.
