From Renovation of the Heart by Dallas Willard:
This impotence of "systems" is a main reason why Jesus did not send his students out to start governments or even churches as we know them today, which always strongly convey some elements of a human system. They were, instead, to establish beacheads of his person, word, and power in the midst of a failing and futile humanity. They were to bring the prescence of the kingdom and its King into every corner of human life simply by fully living in the kingdom with him.
