These are web-sites that I frequent and enjoy and have found helpful.
Daily Dose of Greek (Professor Rob Plummer)
Daily Dose of Hebrew (Professor Mark Futato)
Beggar’s All Reformation and Apologetics (James Swan and his excellent research on Martin Luther and other Reformation issues. I also blog sometimes at this site.)
Cannon Fodder, Michael J. Kruger (Issues on the Canon of Scripture, early church history)
Al Mohler (President of Southern Baptist Seminary)
https://onefold.wordpress.com/ (Brian Culliton’s blog on Roman Catholicism and the Early Church evidence)
Professor James Anderson – Proginosko
Green Baggins – PCA Pastor Lane Keister and other Presbyterians discuss theological issues.
I disagree with David Waltz on a lot of things, but he has a lot of great information on historical theology, church history, and the early church fathers.
A Roman Catholic blogger named Allan Ruhl. I disagree with him on every issue of Protestantism vs. Roman Catholicism, but enjoy reading his blog, and appreciate many of his thoughts on moral issues and when he debates Muslims.
