The Veritas Forum have just launched their new website. Began in 1992 at Harvard, the campus ministry was established to provide a context for students to explore the ultimate questions of life. Today the organization works with more than 60 leading schools throughout North American and Europe, coordinating events with leading Christian thinkers such as Os Guinness, Alister McGrath, Dallas Willard and many more.
The website offers many great videos and resources that I encourage you to explore.
Here are a few:
