Self Defense

Self defense is assumed by most to be a self-evident right. One need only think of the Fifth Amendment to the Constitution that describes the right to avoid self incrimination, or arguments that would allow for abortion to save the mother's life (her own self preservation). It is simply taken for granted that the individual has the right to defend his own life. For those desiring to base their thoughts upon the Bible, there are three areas to explore. Is self defense consistent with the teaching of the Bible? If so, is it personal only, or does it have broader implications? And finally, what are the limits or qualifications that restrain it?
