We intended the lesson to provide guidance in identifying enthymemes, rather than the answer key. From the first example on p. 422, you can see that an enthymeme has at least a declaration, and a conclusion that is somewhat of a jump from the declaration. Armed with that information, you can turn back to the model and see "Keep your conscience clear and God will protect you." That can be easily restated as
I am one with a clear conscience.
Therefore. God will protect me.
Lene is unavailable to give a further treatment of this question at the moment, but hopes to do so when time permits.
