The divine is shaped to the mortal limits we place upon it. It is not inherently limited, only the manifestations in which the divine pours itself from itself. In Christian terms this would be equivalent of putting on the Mind of Christ, the Christ Consciousness (Philippians 2:3-11) all Christians struggle to emulate. To be Christian is to be Christ-like, to allow the transformation within to overtake our bodies being filled with the Holy Spirit. But I am using Christian terms to describe a human experience, a natural experience. The label, the terms, the symbols, and story are merely the vessel into which the divine pours itself. Some may ask why would the divine bother with different types of containers, why would God allow for different religions to spring up. I believe this question is equivalent to asking why nature would bother to produce more than one type of species. The universe is infinitely creative and for the cosmos to not create diverse life would be an incredible waste of energy. The diversity of faiths along with the people who hold them are representative of that creativity.
The phrase A God shaped hole relates to the symbiotic relationship between the sinner and God described within a Christian context: what is a God shaped hole without a God to fill it, and what is God without a God shaped hole to fill? We may feel distant from the divine during times of suffering and loneliness, but it is at these times where we find the divine all around us, permeating throughout all things, all people, and all places. If God is Love manifesting itself through creation then God has never left us, nor will ever leave us.
Psalm 139: 7-10
Where can I go from your spirit?
Or where can I flee from your presence?
8 If I ascend to heaven, you are there;
if I make my bed in Sheol, you are there.
9 If I take the wings of the morning
and settle at the farthest limits of the sea,
10 even there your hand shall lead me,
and your right hand shall hold me fast.
