Volunteering at a soup kitchen or donating new socks to people experiencing homelessness aren't bad things to do.

They're just not enough.

So says Jim Wallis, a bestselling author and speaker who appears across the United States and abroad. He'll be in town for Interfaith Hospitality Network of Greater Cincinnati's interfaith breakfast on Dec. 5 at Crossroads Church in Oakley.

The theme of the event is "Faith in Action: Living your spirituality to help others," and it's a message Wallis has been spreading for decades as the founder of Sojourners.

"Getting people involved in service, it's an opening. It's a welcome way into getting your world view changed," Wallis told me. "But unless it raises questions, it loses its potential to change our world view."
