True faith always produces real conformity to Christ.

Every sin is an act of cosmic treason, a futile attempt to dethrone God in His sovereign authority.

I do not want to drive across a bridge designed by an engineer who believed the numbers in structural stress models are relative truths.

The concept of divine revelation was central to Augustine's epistemology, or theory of knowledge.

The metaphor of light is instructive. In our present earthly state we are equipped with the faculty of sight. We have eyes, optic nerves, and so forth- all the equipment needed for sight. But a man with the keenest eyesight can see nothing if he is locked in a totally dark room. So just as an external source of light is needed for seeing, so an external revelation from God is needed for knowing.

When Augustine speaks of revelation, he is not speaking of Biblical revelation alone. He is also concerned with "general" or "natural" revelation. Not only are the truths in Scripture dependent on God's revelation, but all truth, including scientific truth, is dependent on divine revelation. This is why Augustine encouraged students to learn as much as possible about as many things as possible. For him, all truth is God's truth, and when one encounters truth, one encounters the God whose truth it is.

Our lives say much more about how we think than our books do. The theories we preach are not always the ones we actually believe. The theories we live are the ones we really believe.

The simplistic way of not conforming is to see what is in style in our culture and then do the opposite. If short hair is in vogue, the nonconformist wears long hair. If going to the movies is popular, then Christians avoid movies as “worldly.” The extreme case of this may be seen in groups that refuse to wear buttons or use electricity because such things, too, are worldly.

A superficial style of nonconformity is the classical pharisaical trap. The kingdom of God is not about buttons, movies, or dancing. The concern of God is not focused on what we eat or what we drink. The call of nonconformity is a call to a deeper level of righteousness, that goes beyond externals. When piety is defined exclusively in terms of externals, the whole point of the apostle’s teaching has been lost. Somehow we have failed to hear Jesus’ words that it is not what goes into a person’s mouth that deflies a person, but what comes out of that mouth. We still want to make the kingdom a matter of eating and drinking.
