Deb,
You are correct. Baptists and Presbyterians both follow Calvin, who claimed that we were totally corrupted as a result of the fall and that we could not even will to do good (thus, no free will). Thus God decides who is to be saved and who is to be damned, and there’s really nothing you can do about it if you are in either camp. This doctrine seems so repugnant that it’s odd that people would embrace it, but many do (or did). At any rate, the churches you mentioned depart from calvin on the doctrine of free will, and believe that we CAN choose to do good or evil.
Under the Mercy,
Phaedrus
