Greenville Presbyterian Theological Seminary has hosted many great resources, sermons and lectures online that is a tremendous blessing to the body of Christ.
They recently have loaded up online lectures concerning Old Testament Biblical Theology as taught by Dr. C.N. Wilborn, who gave the recorded lecture in 2009.
Though my theology is not Presbyterian, nevertheless I do hope to listen to them and get to learn from it.
Here are the MP3s to the thirteen part series.
