I've been checking out several blogs and web sites lately, and I found another great "one-stop-shoppping" Bible study resource. Just about everything you need for lesson preparation (resources, references, and Bible study tools) is available at this site.
Called The Smart Christian, it encourages a thinking approach to Christianity. Good stuff!
You'll find the SmartChristian.com page devoted to Bible study tools here. You'll find the site's theological resources here. You'll find other general reference sources here.
Don't forget to check out the history reference link and other resource links offered at this site. You'll find a ton of neat study aids.
That's it for now,
