A bible, prayer asking for God's Spirit to be our teacher and faith in God's Word
Of course all we need is a bible and prayer to God that he will be our guide and teacher and faith in God's promises that he will answer our prayers and teach us His Words according to the new covenant promises of John 16:13; John 7:17; John 14:26; 1 John 2:27. This is a part of God's new covenant promise in Hebrews 8:11 from Hebrews 8:10-12 from Jeremiah 31:31-34 and Ezekiel 36:24-27. These promises of course according to the scriptures are all conditional on us seeking *Jeremiah 29:12-14, and continuing in "believing and following" what God's Word says (see John 8:31-36). So all we need to study Gods' Word is a bible, prayer and faith that God will guide is and be our teacher and nothing else is needed!
Useful digital tools for studying the bible
We do not need any of these things here to know God's Word but sometime there are also excellent digital tools and free online resources available that can help improve the study process as we seek God's Spirit to be our guide and teacher. Some of these tools are very expensive while others are free or at minimal cost to purchase. This part of the forum we are wanting to list what has helped you...
For me personally, I have the expensive software Logos with all the bells and whistles that most people will never use but to be honest I hardly use it and my preference that I use most of the time is free software and free online websites. So for me personally, I mostly use the following that has really helped me with God's Spirit to learn God's Word and includes mostly free software with cheap customizable add on modules. With Logos you pay for a lot of things you do not need. So to the free stuff I personally love.
Free and low cost affordable for everyone
Bible Analyzer - Free software that is awesome by itself and come with many free add-on modules making it a very powerful tool for studying the bible. Fully customizable meaning you can add other modules to the base program very cheaply so that your only paying for features you will use and not paying for things you will never use. Beside all the free modules you can add to the base program you can also add low cost modules that link directly into the program. The layout of the program is fully customizable to how you would like to use it. You can take notes, link other Hebrew and Greek study resources, dictionaries, Lexicons and Interlinear modules making it a complete digital study package.
Bible Hub - One of many online but one of my personal favorites. It is not as powerful as the previous but is also a very useful study tool to use with your bible. It also includes bible online that you can use and it is all free.
