Hasn't the message already been sent many times?
If the world didn't need saving, would a messenger be sent?
If the world needs saving, surely many have already rejected the message many times.
Why would they accept the message now?
Yes it has been sent in many ways in many ages.
I see decay is built into this creation, thus religion is and will always always be a cycle to be renewed.
The rejection brings about the required change, that is the organic aspect of faith. In this age we have been told that great change will happen. We have always been given a chance before the event unfolds.
The warnings have been given and as you noted have been ignored. The world today will not be the world of tomorrow. Materialistic tendency has tipped the balance and there is not turning back.
What can be said to those that do not want to hear? Nothing really.
