What book could you read over and over again?
You may call me weird but I rarely reread books.
Once I read novels they are passed on to friends or boxed up to donate to various charities.
I do hang onto some non-fiction books for reference purposes.
BUT…
I own hundreds of children’s books that have been read and loved since my adult children were wee babes.
On a more serious note, for the last several years I have read through the Bible. Each year I read a different translation. I have used many different reading plans including chronological, mix of Old Testament & New Testament, beginning to end and topical. This habit has been made easier with apps like YouVersion & Through the Word.
My advice is to find a translation that works well for you and READ IT!
All Scripture is God-breathed and is useful for teaching, rebuking, correcting and training in righteousness, so that the servant of God may be thoroughly equipped for every good work. – 2 Timothy 3:16-17 NIV
