E-Sword is a very useful free tool you can run on Windows that helps you in your Bible study. There is a version for MacOS as well, but it is not free.
Free Resources
Below, are also listed various resources that I believe you may find helpful. Some are on this site and some are links to other websites.
The church at Dowlen Road in Beaumont, Texas, has been putting out high quality helpful material for years. You can get a lot of good from what they have available.
BibleHub has an amazing amount of Bible study tools available. You can read the Bible in many different translations, see the original languages and what the words in those languages mean, read commentaries to see what others think the passage you are looking at means, and even see maps of places you are reading about in the Bible!
The Word is a really useful Bible study tool for Windows. I tend to prefer using it more than E-Sword for the slightly better search capabiliites, but both are very good.
