Alan Knox continues to post on the theology of encouragement in Hebrews in his post, Encouragement as Trajectory in Hebrews. He argues that Hebrews has both a negative trajectory (encouraging his readers to move away from something) and a positive trajectory (encouraging them to move towards something). He continues with another post on Mutual Encouragement and Admonition in Hebrews 10:24-25.
Jason Whitlark, a current colleague of mine at Baylor, reviews a book by Kenneth Schenck, a former colleague of mine from my Asbury Seminary days. :-) Ken's book, based on his doctoral dissertation at Durham, is entitled Cosmology and Eschatology in Hebrews: The Setting of the Sacrifice.
