A concordance is the first thing to reach for when you want to explore the Bible in-depth. Organized alphabetically, it's a word-by-word index of the specific Bible translation you're using. When you can't find a Scripture passage or verse you're looking for, turn to your concordance. It's absolutely essential for doing word studies, and great for topical studies as well.
