Understanding the Bible: 3 John
Third John may contain only fifteen verses, but it raises important questions about truth, health and prosperity, hospitality, Christian mission, leadership, reputation, and faithful living.
These focused studies are designed to help you slow down, ask the questions thoughtful Bible readers naturally ask, and explore the historical, theological, and biblical background behind John’s shortest letter.
Questions That Help You Understand 3 John
Understanding the Bible studies are not traditional verse-by-verse commentaries. Each article takes one important question raised by the biblical text and follows it more deeply through history, context, theology, and related passages.
Use these studies alongside the Foundations, Leader, and Deep Roots commentaries to explore the questions that deserve more attention than a normal commentary section can provide.

Careful Bible study does more than identify the main idea of a passage. It notices details, asks questions, follows themes across Scripture, and seeks to understand why the biblical writers chose the words and examples they did.
Understanding the Bible is designed to help you develop that habit.
The goal is not simply to collect answers. It is to become a more careful reader of Scripture, grow in confidence interpreting God’s Word, and see more clearly how every part of the Bible ultimately leads us toward Christ.
Understand the Bible. Follow Jesus. Help Others Do the Same.
