Pilgrim

What you might call "maturity" when it comes to John Piper; I don't look at in that manner. Though I would say that I try to look at the evidence when I read something and that has nothing to do with who said it.
Whether it is you, Edwards, John Piper, RC Sproul etc... I believe it is my responsibility to be like a Berean and examine the Scriptures to see if what they say is true. The key being that the Scriptures are the only infallible source of truth.

I have done this for years now and have found that as God is pleased to shed more light on a subject, I sometimes need to change a previously held view.
Perhaps this is maturity, but I think it is also something that should be characterized in every Christian.

Thank you for the link, as I have time I plan to spend some time reading it.

I thought I would also state that the link I provided does have some Edwards quotes to which I am not completely sure how to take. But that might just be because some of what Piper and what Edwards said seem to be a little abstract.
When I read things that seem abstract to me, in order to understand it properly I need to read it a few times.
One of the things I have found in reading people who critique Piper’s form of Christian Hedonism. Is that in a few cases they can’t get past the word “hedonism”. They look at this word and they automatically think of it in the negative sense; rather than in the way Piper means the word. As a result what they are critiquing isn’t an accurate depiction of what Piper teaches. At least, if I understand the issue properly.
Piper acknowledges that hedonism focused on oneself without the glory of God the ultimate object, is sinful. Yet, he believes that when we as Christians truly love ourselves, we seek to glorify God in everything we do; and the direction of how to do this is by getting to know Scripture.
I believe Piper puts the cart before the horse here, in that I think our focus should be on God as directed by Scripture and if we get joy from this, it is something that is a fruit of it.
Loving God should come first, not loving ourselves. Piper however, doesn’t believe that it is possible to not to love ourselves first and he also believes that this isn’t necessarily wrong, when its goal is to glorify God.

A possible danger I find in Piper's approach is that no matter how well intentioned we are, the moment we seek "self love", we are in danger of falling prey to the flesh. However, if we seek to first understand Scripture and put it to use, we are less likely to give in to the flesh.
As Scripture says, whatsover is not of faith is sin. I am not sure how first loving ourselves fits with this, when self love is focused first inwardly. Faith is directed towards Christ alone, not us.
