Bible Quizzing is great, because you always know exactly what to study. We even break it down by week for you! But sometimes there is a specific topic or idea that you want to learn more about. You can try word studies by using a concordance, you could try asking questions of your coach or youth pastor, you could even try Googling the issue. But a Dictionary of Biblical Theology is a great place to start. It lays out an issue, a person, or an idea clearly and cites a number of different experts, if there is disagreement. It's a quick way to go from ignorance to expert.
