When I talk to unsaved people about the rapture and world events, 90% of them agree with the validity of Bible prophecy. Most of them even admit that we are headed towards the tribulation hour. If I try to tell them we might be getting near to the end, that's when I get strong opposition from them. "Not in our lifetime," is the average reply I receive. I always try to reason with them by saying, "You agree Jesus is coming back, and the likelihood of His return only increases each year. Because there is nothing to prevent Him from returning, why not at least be open to the possibility?"
A large portion of the population strongly refuses to consider the prospect of prophecy being fulfilled in our generation. In all honesty, many of these people probably have a good reason for not wanting to see the end times: the start of the tribulation would signal their doom.

In most wars in which two main forces are at odds, it's historically common for fighters to realize they're on the losing side and then defect to the side that's winning. This is particularly true in tribal conflicts. If you're not in Jesus' camp, you're on the losing team. For the time being, sinners still have the opportunity to abandon their loyalty to Satan and to realign themselves as soldiers in God's army. Once Jesus returns to earth, it will become too late for someone to change his or her allegiance
