The Bible tells that you can't have heaven without Jesus, and you can't be saved without him. And here Jesus warns the disciples of many things to come in the future including deception and destruction. We still need to expect these things today.
Mark 13:5-8
Mark 13:5 - 13:8
5 And Jesus began to say to them, “See that no one leads you astray. 6 Many will come in my name, saying, ‘I am he!’ and they will lead many astray. 7 And when you hear of wars and rumors of wars, do not be alarmed. This must take place, but the end is not yet. 8 For nation will rise against nation, and kingdom against kingdom. There will be earthquakes in various places; there will be famines. These are but the beginning of the birth pains.
