How can I be closer to god without having a bible?
dmitriy555 [2]

I'm a pastor's kid and I ask myself that question all the time, and what helps me the best is to go to church and listen to the pastors, listen to praise and worship music, and what I would recomend the most is downloading the bible app on your phone, because most often we are on our phones than reading paper, and personally I've read more of the bible on my phone than the actual book.
