Do you believe in TRIBULATION?

I also believe in tribulation because as you said, it's written in the Bible. It will be the worst time ever happened to mankind. If the things we are experiencing right now is difficult, then the tribulation period I think will be 50 times more difficult than our time. We have food shortage in many parts of the world. Crude oil prices is continuously going up and many more problems and troubles. The tribulation period will definitely be bringing so much pain and hardship to many who will be left behind and experience this time!
