One of the things our youth group kids have asked for is a Bible that can truly become their Youth Group Bible. 🤍📖

We would love to have a large Catholic journaling Bible that stays in our youth room, where our kids can highlight Scripture, write prayers and notes, and mark verses that speak to them!

Our hope is that over the years, it becomes filled with the handwriting and favorite Scriptures of so many of our young people! Turning into something future youth group kids can open and see how God has worked through those before them!

We’ve added the Bible to our Amazon Wish List. If anyone feels called to donate it to ICOM Youth, we would be so grateful! ❤️
