Looking for a good systematic theology to supplement our study in 2013? Here are few great options...
Systematic Theology, Wayne Grudem: Comprehensive, biblical, read-able.
Doctrine, Mark Driscoll and Gerry Breshears: Not quite as academic as Grudem's text, but very accurate and read-able. (By the way, Grudem endorses it!)
Christian Doctrine, Millard Erickson: Have Grudem and Driscoll? Love to read a different perspective? Erickson is orthodox and balanced and provides a different look at systematic theology. I own it and love it.
Each of these texts are more overviews. As we continue our study this Spring, I'll continue to post more specific suggestions (e.g. texts specifically related to Christology, pneumatology, etc.).
Hope these help!
