I thought I knew Wallis, having followed his "career" for several decades.
This was illuminating, even to me.
Any credibility Wallis had, even as a Christian with whom I disagreed, was lost when he refused to take up the issue of the Sudanese Christians (who were also under threat of genocide) during the 1980s and 90s.
Apparently only Muslims in Africa are suitable subjects for his concern.
Let me tell you something else, learned experientially first hand after living in Africa: the problem is not poverty of the flesh, it is poverty of the soul.
Only when the spirit of Christ, and his call for Holiness are imbedded within the African culture will they begin to overcome the devastating poverty of the flesh.
