The first thing to get clear about Christian morality between man and man is that in this department Christ did not come to teach any brand new morality. The Golden Rule of the New Testament (Do as you would be done by) is a summing up of what everyone, at bottom, had always known to be right.
C. S. LewisThe command "Be ye prfect" is not idealistic gas. Nor is it a command to do the impossible. He said (in the Bible) that we were "gods" and he is going to make good his words. He will make us into a god or goddess, a dazzling, radiant, immortal creature...a bright stainless mirror which reflects back to God perfectly.
