The Change in the Belief System

Hi, hello. I was just reading a trend on twitter devoted to apparently bashing Christians because several thought that the world was going to end today. I think that it is really horrible for people to have thought that when it clearly states in the bible that we are not supposed to try and predict the day of Christs return. There are lots of prophecies in the Bible that have not yet been fulfilled about the end. Before His return we will see a one world leader, the same currency for the whole world. The price of wheat (or I guess food) for a quart (I think) will be a days wages and there will be successive natural disasters and turmoil. So far we have just seen the beginning of all of these things. No one knows for sure the day of His return not even the Angels in Heaven with him only the King knows the day so therefore we should just always prepare ourselves and be Servants of the King doing whatever he would like us to do no matter what it will cost us. It bothers me that because of this little fiasco with some Christians so many people won't believe in God because now they think that He for sure doesn't exist and also the Christians who thought that maybe won't even believe. I feel as though this is the exact reason why God said specifically that we shouldn't try and predict when Jesus is going to return. NO one, especially none who are on Earth can know the time and day.
