Good day to you mam. Our belief in God is not so simple if you take it as a whole. It would take books to write on certain specific topics. You cannot explain it in one paragraph on the totality of the Christian faith. The Bible is not composed of one paragraph or 10 pages. To know Gods truth is to study it diligently. Im not saying or bragging that I have studied everything in fact I just knew how little I know and how much more that I need to study about the truth of God. the truth of God takes a life time to study.
There are a tons of presentations and documentary about true christian belief.
There are also a lot of principles that we need to follow that is based on the bible and one of these are health principles.
Just to give you a slight insight about the christian health principles you can listen to this presentation for starters.
Miraculous Medicine, Pt. 1
God really wants us to be healthy in mind and body if you dont want this presentation message then its fine I can provide more topics.
