There is a thread with the question:
"Is there a God?"
For someone who does believe in God, a much more interesting question is,
"What is God?"
I personally find that an exciting and empowering question. Maybe a life changing one.
How do you learn about God?
One important way is through ones experience of God.
And that experience of God may have infinite expressions based on the individuals having the experience.
Yet, I am guessing there are some basic truths about God. One core truth, I would imagine, is that God is love.
Many people seem to have beliefs based on what the religion and culture they were born into. Although, this is changing.
One suggested approach to knowing God better, is to view the your relationship with God as a partnership. Rather than, seeing God as some kind of superior being.
