If you're looking for a great Bible, I use the Life Applications Study Bible (New Living Translation). I use it to study God''s Word, grow in faith and get a closer relationship with Him.
I love this Bible because it's easy to understand and has study notes (words of wisdom) at the bottom of each page that help me overcome my daily struggles.
The study notes also explain the meaning behind a lot of the scriptures in the Bible that are difficult to understand.
In order to write testimonies on specific topics, I need to do some topical research.
In my pursuit to find a great book that helps me do this, I came across The Complete Topical Guide to the Bible.
It lists all the scriptures in the Bible under specific topics so you can learn a lot about each one and easily study specific subjects and themes of interest.
And it's better than a concordance because concordances only list scriptures that use the same word, whereas The Complete Topical Guide to the Bible uses scriptures that include related words with the same or similar meaning.
It's perfect at helping you learn more about God's word at all stages in your Christian growth.
