LANSDOWNE, Va., April 21, 2012— Evangelical Christianity lost one of its most eloquent and influential voices today with the death of Charles W. “Chuck” Colson. The Prison Fellowship and Colson Center for Christian Worldview founder died at 3:12 p.m. on Saturday from complications resulting from a brain hemorrhage. Colson was 80.
A Watergate figure who emerged from the country’s worst political scandal, a vocal Christian leader and a champion for prison ministry, Colson spent the last years of his life in the dual role of leading Prison Fellowship, the world’s largest outreach to prisoners, ex-prisoners and their families, and the Colson Center, a teaching and training center focused on Christian worldview thought and application.

I’ve been privileged to serve as a volunteer with the organization that God led Chuck Colson to fond shortly after he got out of prison for his Watergate Related crimes.  I’ve been involved in many organizations and businesses in my life, never one that had the singular focus or high standards that I found in Prison Fellowship Ministries.  I never met Mr. Colson, but I saw the vision that God had given him reflected in the leadership and in the volunteers and in the work that God did through all of those involved with the ministry.  Only eternity will recognize the lives impacted and changed because of the humility and faithfulness of Chuck Colson.

The following video, posted on the Prison Fellowship website, tells his story better than I ever could.

I know that tonight every person who’s ever volunteered with Prison Fellowship, every inmate, ex-inmate or their famililies whose lives have been touched and forever changed because Chuck Colson heeded God’s call for his life is feeling the same loss my wife and I feel now. Chuck Colson was just family and while we celebrate his home going, we are overwhelmed with a sense of loss.

Well done good and faithful servant. I certainly can’t say it better than that.
