What’s the first thing you do with a Bible after you purchase it? Look up your favorite verse? Write your name on the first page? Hit someone over the head with it? (just kidding, please don’t do this)
If you want to make your Bible last a long time, the first thing you do once you get it home (or before you wrap it up as a gift) is to stretch out the binding.
Hold the closed Bible in one hand with the spine flat on a table. Then hold all of the pages together and let the covers slowly fall to the table. Next, take a section of pages from the front of the Bible and lay them down, running your fingers across the top page, near the crease, pressing gently. Still holding most of the pages upright in your hand, repeat, taking a section of pages from the back of the Bible. Continue repeating this process, first on one side and then on the other, until the entire Bible has been opened into two even halves.
This way, the binding will be flexible and less likely to crack, lose pages, etc. I use this trick for all textbooks too–any book could benefit from it, but higher-cost, high-usage books like Bibles will benefit the most.
