God is a personal being. The Bible is the only source of spiritual truth. The Bible contains history, poetry, theology, and prophecy. The Bible is perfect as written in the original languages. If you have an NIV Study Bible you'll see footnotes sometimes that say, "This verse is not found in the oldest and most reliable manuscripts."

You become a Christian when you repent of your sins, accept what Jesus did on the cross as payment for those sins, and you accept Jesus as your Lord. That means you do the best you can to live a holy life and to do what the Bible commands.

If you follow God with your whole heart God will change you into a different and better person in ways that would be impossible through self-effort.

God is not a force. You can't create your own reality. Crystals are nonsense. Occult objects are dangerous. There are no such things as nature spirits or fairies. They're all demons.
