While it is true that Christians have been watching for the fulfillment of these prophesies for 2000 years, this is not a bad thing. In fact, it is exactly what the Lord wants. There are many places where Jesus tells us to be constantly watching. In doing so, we keep our priorities straight in whatever generation we are living. When we come to the generation where it actually applies (in full) that generation will have a special blessing in that they will be prepared mentally, physically, and spiritually. In that sense, they will be in a position to help others and may be among those who Paul speaks about when he says, "We will not all sleep, but we will all be changed— in an instant, in the twinkling of an eye, at the last trumpet. For the trumpet will sound, the dead will be raised imperishable, and we will be changed.
Luke 12:37
Blessed are those servants whom the master finds on watch when he returns. Truly I tell you, he will dress himself to serve and will have them recline at the table, and he himself will come and wait on them.
