I just finished reading the excellent book "Eternal Justification: Gospel Preaching to Sinners Marred by Hyper-Calvinism" by David H. J. Gay. In the book Gay explains the Hyper-Calvinistic doctrine of "eternal justification" and why it's unbiblical and detrimental to the salvation of souls. Gay has a sermon series on the topic here:

Presumably the series simplifies the issues and gives an introduction so that people will begin to understand the dangers of the doctrine. For more in-depth information, I recommend reading the book.
I'm now currently reading Gay's other book "Amyraut & Owen Tested: And Found Wanting." It's essentially the renamed and restructured 3rd edition of his book "Particular Redemption and the Free Offer." I'm reading it because I'm curious where he stands on the extent and intent of the atonement of Christ. By the title of the book it seems he likely holds some kind of mediating view that's in between Amyraldism and Owenian Limited Atonement. He has a sermon series on the topic here:
