There is, of course, more than one reason why a Christian shouldn’t ease off of his zeal to live righteously. If a supernatural event does not intervene in the world, one could simply die. Either way the meeting could happen without warning. Better not to have too many embarrassing things to explain (they will be forgiven, but the encounter will not be comfortable).
I'm not a pre-, post-, or mid-trib rapture believer (just don't know), but right now is as good a time as any. That said, it's a good idea to stay ready!
