It’s absolutely true that the essence of God does not change, but the experience on Earth most certainly does depending on where we are situated in time and space.
Those changes are effectuated by God in direct response to that which we are projecting for. Many of us rely on religious texts written thousands of years ago, translated from different languages, and modified for our experience of God.
But the Divine can only ever be experienced in the here and now. For us humans, that means direct connection to our core consciousness – where the Word of God is ever present.
