Our belief in God is the product of our faith. Of course, no one currently on the planet earth can say he/she has seen God but we just believe he exist. Spirituality can be trace back in the bible to the trinity God. God the father, son and holy spirit.
I sometimes thought about if there exist God but i change my orientation due to happenings around me.
when someone die what next?
why should there be death?
This and more are the more reason why spirituality exist.@reddust
