Amazon keeps suggesting Concordia publishing stuff in my cart, and I've always had a soft spot for Lutheranism. The stuff they suggest is on 2 Kingdoms, culture, manhood, vocation, discipleship, and the cross. From my (limited) understanding, so long as I steer clear from sacraments, worship, and the Law, they're pretty solid. Have any of you benefited from Lutheran resources and not just Luther himself? If so, how? And what would be the best to look into first?
