I think that while Paul Washer and Charles Leiter are generally good teachers; each with a hiccup or two (as many of us may have); but I find Charles Leiter has one disturbing caveat in his teaching: his understanding of Romans 7.
Within his attempt at exegesis on Romans 7, Leiter asserts that Paul is actually describing his UNREGENERATE self , especially with regard to the words of Rom 7:14-25. Leiter treats this as if Paul was recalling the process of his conversion, rather than Paul squarely affirming this is what he is (in his present setting) wrestling with.
The importance you say? Well, this would corrupt quite a bit (if not all) of Leiter's teaching on sanctification. Also, it seems to lean him closely to some sort of perfectionism, that others such as Zac Poonen ascribe to. While Leiter is a brilliant theologian, this one thing would have me advise you with caution with regard to his teaching on sanctification. But, as with any teacher; test all things.
We have previously made mention of Paul Washer, so I wont go into any more detail about that matter. I hope this does cause you to give thought to these things.
