Much of it focuses on Daniel 9, and its application to the contemporary church (especially 'Brethren'). While understanding that Daniel was writing under a(n obedience-based) Law Covenant - as a member of that covenant nation - and plenty of "disenfranchised assembly guy" stuff not withstanding, he still makes some awesome (and honest) points.
My favorite part follows (reprinted without permission):
Daniel 9 is well worth examining, but I want to point out what is to me the most outstanding feature: Daniel was personally guilty of none of the things he confessed. Daniel himself had not committed the idolatries and immoralities he confessed; he had been only a boy when taken from Jerusalem by the Babylonians, and had an impeccable track record when in Babylon. Further, he was decidedly separated from the rest of Israel while in Babylon. But despite his personal blamelessness in the sins he confesses, he insists on saying "we".I find this striking, because my experience in "brethren" has been precisely that they see themselves as somehow blameless in the current state of things, because they "walk in separation". But Daniel---one of only a couple men of whom the Scripture recordsnot one sin---falls to his knees and says "we".This is the great failure of "brethren" in my mind: that having seen the deplorable state of the Church, they have refused to humble themselves and confess it as "we". They've been quick to separate from sin they see, even if it means separating from other Christians; one would think that might mean they understand the seriousness of sin. But they have refused to acknowledge that we are all One Body, what one member does, all feel. Their fine-tuned rules of fellowship and separation have sprung from an admirable sense of wanting to avoid evil: but they have failed to see the big picture; we are in this together.
