Holy means the pure, loving nature of God,
separate from evil. aggressively seeking to universalize itself: that this character

Therefore, we need to separate ourselves from evil, by not associating with evil, being
found in a situation where one could get the idea of being evil. That doesn't mean to not
have any friends that are not Christians, for even Jesus spent time with the social and
religious outcasts of His day. When we associate with those people our behavior needs to
demonstrate that we are different from the people or the evil things surrounding us at
that given moment.

may be one, as we are.
And the four beasts had each of them six wings about him; and they were
