Good bible study and message development requires a decent commentary. Trust me not all commentaries are equal, authors write based on the prism they view the world through, so you need to find a good commentary that aligns with your doctrine and theology. Good commentaries should be exegetical or expository in nature. My favorite is the Expositors Bible Commentary, my mentor prefers the IVP series. Find an author that you connect with and use it. Here are some good examples:
Expositor’s Bible Commentary
IVP New Testament Commentary Series
Word Biblical Commentary
New American Commentary
Tyndale New Testament Commentary
New International Commentary on the New Testament
Early Church Commentary
