Mankind is by nature fallible (i.e., not immune from making mistakes) and finite (not infinite, particularly in knowledge like God has). In subcultural and countercultural views of reality this inherent condition of mankind is regarded as the reason why mankind can never have certain knowledge, which in turn leads to the equally mistaken idea that all individual and collective authority must therefore automatically be mediatorial in order to maintain some semblance of order in society, even if this means oppressing and dominating others. The entire Fallen World System is nothing but one huge civil war between subculturalists who fear oppression by fallible and finite collectives and counterculturalists who fear the social chaos of fallible and finite individuals. The kingdomcultural alternative does not fear the fallible and finite realities of humanity but embraces them as exactly the condition that makes possible certain knowledge if in boldness and humility, following the example of Christ in his kenosis, we operate as faithful delegated authorities who make God’s revelation of the Word in creation, Scripture and by the Spirit the starting point and foundation of our own knowledge. In this approach, while we are fallible (and thus not immune from making mistakes) we can operate inerrantly (without making mistakes). And while we are finite (and thus do not inherently have comprehensive knowledge which is the necessary condition for certainty) we can be certain about what we know because we base our finite knowledge on the sure foundation of God’s revealed knowledge, which is certain because He knows all things exhaustively.
