I have previously compiled several remembrances of and tributes to J.I. Packer, who passed away in July of this year. Those can be found here. I want to add a couple more.
The first is by Alan Jacobs (whose blog happens to be the only one that I take the time to read every post). His remembrance is brief and personal and captures some of why Packer had such a wide influence and why the church needs more people like him. Jacobs' tribute can be found over at Snakes and Ladders.
The second is a compilation of several remembrances and tributes to Dr. Packer, from colleagues, publishers, former students, friends, fellow theologians and Bible scholars, etc. There are contributions from many, including Alister McGrath and N.T. Wright, as well as a former student of Dr. Packer who also happened to be one of his care-givers in the days leading up to his death in hospital. This video memorial can be found here.
