In this piece Chambers doubles down on his comments. You can also hear the perspectives of Russell Moore, Michael Horton, and Ben Witherington---all of whom express serious concerns about the antinomianism they are hearing.
I still think Denny Burk put this pretty well: "It appears that this has less to do with Chambers' views on homosexuality than it does with his views on salvation. Chambers still affirms a biblical sexual ethic. He simply argues that Christians can ignore that ethic and still be considered Christians. It sounds like the non-lordship view of salvation that was made popular by Zane Hodges."
For a primer on this issue of so-called Lordship salvation, see this older article by S. Lewis Johnson.
