Deeper Waters - Nick Peters; blog and podcast (Christian theology and apologetics)
Deeper Waters is a very useful ministry. In addition to the blog is a podcast that consists primarily of informative and entertaining interviews with many great apologists and scholars. Episodes focus on everything from the standard apologetics questions (the problem of evil, the historicity of Jesus's resurrection) to niche topic like the biblical allegories in Harry Potter that you may not find in your traditional apologetics podcast.
RethinkingHell - Multiple contributors; blog and podcast (Christian theology)
The Rethinking Hell blog and podcast focus on the topic of final punishment, asserting and defending the conditionalist/annihilationist view (as I do in The Bible Teaches Annihilationism). A number of evangelicals from different backgrounds, often with their own blogs and podcasts, contribute. I think they do a great job - and I don't just say that because I am a contributor myself ;)
