Lordship Salvation

I'm writing a paper for Systematic Theology on the Lordship Salvation debate. I had never looked into this before, but my professor briefly mentioned it in class one day. Then I was talking to Dad about what I should write my paper on, and he actually mentioned the Lordship debate. I have no idea what even made him think of that!! So it has been fun to go back and forth with him on this subject. I am finding more sources that defend Lordship salvation (John MacArthur, Gentry, Horton, and many others) than those that oppose it (Charles Ryrie and Zane Hodges). Basically, those who defend Lordship salvation say that in order to be a Christian, one must not only believe in Jesus as Savior, but he must also confess Him as Lord. Some people confuse this and say that we must make Him Lord of our lives. We cannot make Him Lord, as He already is Lord, and God made Him Lord. But we do need to confess Him as Lord and recognize that authority in our lives. Those who oppose Lordship salvation say that one only has to believe in Christ as Savior, but the word LORD does not mean "authority." My response to this: even the demons believe...and shudder! Romans 10:9-10 says we must confess Him as Lord and believe that God raised Him from the dead and we will be saved. I know the differences in this debate rest on the definition of "Lord", but if someone is not willing to confess Jesus as Lord and recognize that authority in his life, how can he truly be saved? The more I study throughout my life, the more I realize that I don't know or understand...it's still fun to study though. The crazy thing about this debate is that John MacArthur said that whoever is teaching the wrong thing is sending people to hell since whichever way people believe affects how they evangelize. Scary.
