The Tyndale Old Testament and New Testament Commentary series sits in a very useful middle ground: more depth than a study Bible, but far less technical than many academic commentaries. The volumes balance historical and literary context, exegesis, theology, and practical relevance in a format that is still accessible to thoughtful lay readers.
The full series is a significant investment, and unless you are headed to seminary or doing serious long-term study, you probably do not need to buy the whole set at once. If your church teaches through the Bible book by book, consider buying the coordinating volume as you go.
Also remember that commentaries are more like encyclopedias than ordinary books. You do not have to sit down and read one straight through. Use them when a passage raises a question, when you want to compare interpretations, or when you are preparing to teach. Tyndale is a great step up when you want more depth without immediately jumping into the heaviest academic literature.
