With God, we have His word, the bible which is the word of God.
We can trust it because we can apply it in our lives and see how it transforms us.
When we accept Jesus Christ in our hearts and follow His teachings there is hope for us in this chaotic world.
It's a relationship with Jesus, not a religion.
The Bible gives us peace and hopes that the world can't give us.
The world won't believe it and is not able to do because it's spiritually discerned.
Without the Spirit of God in us, we try to do it our way until we come to the end of ourselves and say get me out of here, like suicide, addiction, etc.
We can trust the bible because of the prophecies that have come true and the promises that God has given us for hope and eternal life.
No other religion can give you that.
The world will use many principals of the bible, but will leave God out of it.
