I don't believe that is necessarily true, or that we need to focus on destruction.
Quotes from Revelation, The Birth of a New Age by David Spangler, channeling an
entity calling itself Limitless Love And Truth. (pub. 1976):
"You are coming to a time when, to an increasingly greater degree, you will
be able to manifest and create through thought and feeling. You already
do this, but your power in this is being augmented. You have termed it instant
manifestation; it will become far more instant than you believe is possible."
"The new heaven and the new earth shall emerge, not in conflict with the
