See my post nr. 60...
I think people who love the teachings of Christ should not be condemned, but rather encouraged.
A dear friend of me brought me to Christ that way...
It wasn't my intention to condemn people who are "on the road" to Christianity yet have not yet arrived. It is rather concern for such people that is behind the argument. I personally can't think of a greater tragedy than those who never cross the Jordan river, but rather sit on the opposite bank and are content with their view of the Promised Land. For how sad is it to look upon the fruits of salvation but never taste them?
Your point, however, is helpful to me. I do think that my language on this subject can (as Lewis' does) get a bit jaded, perhaps matching perceived condescension with condescension. Thanks to your comment, in the future when I employ this logic, I will determine to do so with gentleness and caring, so as to draw the listener further onward, rather than forcing their hand, and possibly turning them away.
Thanks for the response.
