Introduction — A Reformed Approach to Science and Scripture

A nice balanced answer by Sproul: Introduction — A Reformed Approach to Science and Scripture by Keith Mathison | Ligonier Ministries Blog:

...the speakers were asked this question in connection with the ongoing debate between Christians who think the universe is less than 10,000 years old and those who think it is much older. Dr. R.C. Sproul took about five minutes to answer the question, and what he said in that brief period of time should be heard by every Reformed Christian who is interested in this subject and by every Reformed Christian who is discussing and debating it.
