The Narrow Path Ministries

is there any way to find out what a specific "narrow path" radio show is for a certain date?

Only by listening to it as far as I know!
I've tried to keep a record as I listen [on an excel sheet for some reason] for my own reference, WHEN I remember. I have only managed to think to do it for about 20 episodes ranging from 2006 to this year.
eg.

25/04/2008 Jim (Torrington) objection to RC Tom's call re Calvinism being sin & heresy to 11 min.
Carna - gifts of the Spirit cf natural talents / fruit of the Spirit to 30 min
Ben - Heb 13:9-16 re meaning applied to us of sacrifices/going outside the camp to 44
Curtis - comparison of Paul's meaning of law in Phillip & Romans (pharisee v. christian appl) to 49
Jeremiah - re substitutionary atonement

27/09/2006 preterism
christian music industry history

hmmm...there's a lot of programs. i've only listened to 1 episode, but many lectures. it seems like mr. gregg gets really amped when he lectures. what are the radio shows typically like?

Well, the format being that of responding to callers’ questions, they can vary a lot, though inevitably there is some repetition of content, since not all callers would have heard previous shows discussing the same thing.
(I also find this a valuable way to test my acquired knowledge. Sadly, my memory seems abysmal at times & repetition does me good!).

As well as some current issues people bring up, there are sometimes requests for advice for specific life situations.
Personally I find the radio show interesting and instructive, and I also have listened to many topical & verse by verse lectures.

I guess the best way to find out what they’re like would be for you to listen to a few episodes.
