Videos on Calvinism, Free will, and Open Theism

I have been watching a number of videos on the Realityisnotoptional youtube page, one that is dedicated to teaching and discussing Open Theism and related issues. Here are some videos I have been watching this morning which are rather informative:

Ep134 - Arthur Haglund on John 6 and Matt Slick

Ep138 - Free Will - Pagan and Unbiblical

EP162 Perseverance of the Saints response
