online study tools

Here are the standard sites that I typically use when I'm preparing for a sermon:

www.biblegateway.com - great bible search site

www.blueletterbible.com - basically all the Bible study tools you need

www.biblestudytools.com - i particularly love the NAS with Strong's Numbers but you can also click "include study tools" and it'll pull up commentary on each verse

http://www.antioch.com.sg/bible/vines/ - online Vine's Expository Dictionary of NT Words

www.dictionary.com - self-explanatory plus their thesaurus site

what are your favorite online resources?
