The Law of Liberty & Freedom!

James 1:22-25

As important as HEARING the Word of God is, it is not enough.  Hearing must necessarily be accompanied by action, by doing, by change!  James likens the person who responds thusly to a person who "looks into the perfect law, the law of liberty. and perseveres."  James' view of the Law makes some evangelicals uncomfortable; so what does he mean by the terms?
