There are a few articles that I return to repeatedly because of the unique insight they provide on difficult issues.  The links are provided below:

• Justin Taylor describes levels of doctrine to help us prioritize those issues that really matter in theology
• He also has a nice back-of-the-napkin illustration to prove Jesus’ divinity to groups like the Jehovah’s witnesses
• Tim Challies provides seven rules for debating issues Biblically online to have God-glorifying discussions
• Tim Keller explains how to pray using collects, a method from Thomas Cranmer. Collects are are brief prayers that tie together doctrine with a way of living
• Learning how to study a topic in detail with observation over a period of time to see more an more nuances
• Understand decision making through the lens of Scripture in areas that the Bible doesn’t directly address in When is Pragmatism Prudent
• John Piper explains lessons from the life of Athanasius. His point #4 on using non-Biblical language to explain Biblical truth is particularly important
