President Obama struck a humble tone at the National Prayer Breakfast, the Rev. Joel Hunter said on Thursday. The senior pastor of Northland: A Church Distributed said the President spoke less of his own faith as he has in the past and more about the role of humility in leadership. “We must keep that same humility that Dr. King and Lincoln and Washington and all our great leaders understood is at the core of true leadership,” Obama said in his speech. The president began his address by announcing that his head of the White House Office of Faith-Based and Neighborhood Partnerships, Joshua DuBois, will leave his position on Friday. Ben Carson, a pediatric surgeon at Johns Hopkins University and a Seventh Day Adventist, was the keynote speaker at the breakfast.
