Adrian Rogers or Charles Stanley (I can't remember which) once said that he thought that Bertha Smith, who died in 1988, did more than any other human being to orient Southern Baptist pastors to the Holy Spirit. (Smith was a contemporary and missionary friend of Martha Franks.)
I believe that since Ms. Smith went to heaven, that mantle fell to Henry Blackaby. Few resources have had the massive impact on God's people in the Southern Baptist Convention like Experiencing God: Knowing and Doing the Will of God by Henry Blackaby. I doubt if there is any one living person whose life-message has impacted people in the SBC more the last 23 years.
Lifeway Films, a new division of Lifeway Christian Resources, is about to release their first documentary - one about the impact of EG in the Southern Baptist Convention and beyond.
