By asking.
Average person or average believer? What does "tremendous" have to do with it?
It is a very simple question. Would you say that the average American is a good Christian?
Based on how you define it.
How do you define it?
I don't have a basis, as I don't know their hearts. This is like saying the average gynecologist is a pervert. What is that based on...my opinion, and that's it.
So then you never make any conjecture about averages without hard stats, is that right?
You would not say that the average 8 year old does not know the periodic table, right?
Some do. There's no doubt about that. As far as you know, the average does, right? Because you can't ask all of them, nor do you have any hard stats on the matter.
You would reject the idea that the average 8 year does not know the periodic table because you can't ask them, right?
That's your standard of conjecture concerning averages, right? If not, what is your standard for being able to believe that "the average _________ does ____________"?
I'm not...and I doubt it. I'm an "average church goer" and to me that is an insult. I'm in a church with 250 more like me and I woldn't dare say the "majority" of them are not spiritually mature.
If that is true, congratulations. Would you say that the average church member gives sacrificially to the church and missions? Would you say your average church member has read his/her bible through numerous times?
Would you say your average church member proclaims the Gospel of Christ on a very regular basis? Would you say your average church member is rigorously training, his/her children in the ways of God at home? Would you say your average church member knows where he stands soteriologically, hamartialogically, Christologically, and on Theology Proper?
Because if the answer is positive in all those areas, I think most of us can safely say you attend a VERY above average church.
At any rate, what does this say about the shepherds of the flock?
According to your silly standard here you can't say anything about them until you ask them or know their hearts.
