Bauder on "General Revelation"

… natural revelation, while clear as far as it goes, is limited in its scope. It does not disclose the entire divine nature in all its attributes. It does not divulge a complete moral system. It does not reveal God’s plan, His providence, or the mechanisms by which He created and sustains the world. Though it should convince people that they are lost, it includes nothing about Christ or the way of salvation. It provides no help for ordering either a private life of faith or a believing community. In short, natural revelation is sufficient to condemn, but it is not sufficient to save. It is entirely inadequate as a source for constructing a theology, a moral philosophy, or even a cosmogony.
