The importance of clear articulation

Today I had a pretty interesting encounter in church.Two foreigners came to church today.One of them, a Mr John from Europe approached me and started asking me a lot of questions.Here is an excerpt below
(FG-Foreign guy)


FG::So what do you folks do apart from Church ?
Me:Well we have fellowship every sunday where we meet up

FG:Well dont you guys do anything apart from that ?
Me:Well we witness wherever we are, whenever we get the opportunity

FG:Well what do you think about so many divisions in the Church , there are Catholics,Protestants etc etc?
Me:As long as people are united in the essentials I guess it shouldnt really be a problem

FG:People might not be really united there , what about your belief of Salvation by faith whereas, some others believe
in salvation by faith+works?Dont you think thats a key issue

Me:Yes that is a key issue .Divine sovereignty and human responsibility you take either
of those away and you have a problem, this is an issue which is still held in some tension and I am happy to let it stay that way

FG:Coming to that.Do you believe God predestines people ?
Me:Yes.

FG:So that means you are a Calvinist?
Me:Yes.

FG:So that means you must also believe in double pre-destination ?Dont you think thats unfair?
Me:How Calvinistic was Calvin anyway ?That is a slight distortion.I believe that God is solely responsible for our Salvation and while I believe that God pre-destines people to heaven he does not pre-destine people for Hell.To summarize I would say that if we are saved it is because of God,If we fall then that is because of us.

At this time my mom called and I had to leave him :) .

The point I am trying to make here is that.Try to have not only have a clear understanding of the Gospel but also try practicing a clear articulation of the key points of Christianity.I felt I could have articulated some of the points above a lot better[Quoting scripture,making it clearer, asking him counter questions etc..]

I believe that the person was a Mormon and if I had continued.He would have told me that Joseph Smith had the answer to all of this.I am beginning to lose my faith in these foreign people especially since I had a previous encounter with another foreigner who did the exact same thing.Will it not be better for these guys to preach the message of the Gospel to non-christian people ?
