Gospel Library installation issue

Hi, I currently have an iPhone 6s with iOS 11.1.2, with 33GB storage left on my phone. I was recently told that there was a new update on the gospel library, with new content such as the New testament - Life of Jesus Christ videos. However, the content was not downloading on my phone, so I deleted the app to re-download it. During the process, when I tried to install the app, it continues to say that it was unable to download the item. It seems as if it stops working when it gets to the "installing" portion of the download. I cannot seem to use it and need to get it fixed ASAP - as I will need to use some of the content in the near future. If there is a way to solve this please let me know ASAP!

note: I've tried plugging it into the computer and redownloading it - has yet to work.

Are you installing the app from the regular iOS App Store? You could try restarting your device to see if that fixes things. Also, make sure you're connected to a good internet connection. Are you able to install other apps? If you are installing the app from the iOS App Store, the download and install process is handled by iOS itself (not by the downloading app).

Sorry, I'm not a Apple person, but from what I've read, there's a process of uninstalling that re-installing that has to be done correctly, or else you end up re-installing a cached (and possibly corrupt) version of that app.
