I cannot say I personally knew him, but my HS English teacher knew him very well. She actually went door to door with him in Atlanta canvassing the neighborhoods there. Based on her testimony I would say that Doctor King was definitely a Christian.
That said, no one knows till we get there and this kind of article is completely useless and I don not see how it promotes the Kingdom of Christ. We all need to work out our own salvation with fear and trembling.
Thank-you for making my day with your comments.
