The words, "liberal," and "liberalism" have many meanings; however, here we are referring to an underlying principle that says that all people are basically good. This principle declares its liberty from God and so it is sold to slavery to sin.  It obviously refers to the word, liberalism, as it is used today rather than the classical definition of a liberalism (which was against giving great power to governments and was against many regulations and restrictions of freedom--particularly religious freedom).

In declaring himself to be good, man must re-define the word, good.  That is why liberalism supports so many things that are evil.

The anti-Bible concept of "human goodness" lies at the root of many cults. Jesus said, "There is none good but God."

Liberalism is founded on the supposed natural goodness of humans, which is a false supposition and an attempt to do away with the need for Jesus.
