Dr. Robert Chisholm, Professor at Dallas Theological Seminary, visited Liberty University in the Spring of 2011. His lectures (and responses) were previously posted on this blog. However, the quality wasn't very good (one apparently had no sound). Now the videos are available in much higher quality.
Chisholm on Isaiah 53 (Morning session)
Chisholm on A Biblical Theology of Judges
Response by Dr. Michael Smith (Liberty University)
Response by Dr. Harvey Hartman (Liberty University)
