imho it really depends on our expectations. if we expect that when Christ returns we will immediately know and see His Kingdom erected, then yes, we may be lost...but when in the history of any religion have the scriptures gloriously descriptive unfoldment of events actually happened the way we envision them?
When Christ came the first time, He was crucified for exactly those reasons. It was blasphemous in the eyes of the clergy of the day, for Him to make the claims He made. Basically because it did not occur the way they expected, with all the pomp and glory associated with His coming in the scriptures.
What we should have learned from the history of Christ's life, is that these glorious descriptions actually describe a spiritual reality, as opposed to the material reality. And as such we should be somewhat humble in our approach.
One thing we need to remember is that God tells us that 'His ways are not our ways'.
if we can then change our expectations to see that with His Return, if God stays true to His ways, things may unfold in a similar fashion. Not quickly and with earthly fame and glory, but quietly with spiritual implications taking precedence, then we do not have to be lost, but rather overjoyed at the magnificence of God's ways.
Baha'i's believe that with the Return of Christ in the Glory of the Father, (who we believe to be Baha'u'llah <the Glory of God>) that His coming, set in motion the forces of the universe destined to attain the goal of erecting the Kingdom of God on earth. We believe that everything written in scripture will come to pass, but not necessarily as we would expect. And not overnight, but gradually, as has always been God's way in the past.
my 2 cents.
have a great weekend!
