God is invisible and is untouched by any karma. Though he lives in every human being, in every embodied living being, in their heart, he is not afflicted by the karma. How?
Like the space; in the space clouds come, smoke comes and they go but the space itself cannot be touched. Space itself remains untouched, unblemished. Like that inside us the divinity remains pure forever, unblemished, untouched by whatever actions or inactions we do.
