Now, just to reassure the gullible, there is no such thing as the “God gene.” This is mostly junk science intended to demoralize the simple, and embolden the non-believers.
We know this by both faith and reason:
By faith, because revelation teaches us in Scripture that faith is a grace/gift, and it comes by hearing (not by birth, which would necessitate Calvinist predestination); by reason, because as genes are static, conversion would be impossible (as would, conversely, the loss of faith), yet both are common, observable changes.
Nevertheless, none of this precludes their theoretical ability to poison/semi-lobotomize a brain in such a way that one feels distant and depressed, as many psychotropic drugs do (and consequently, when thinking or praying to or about God, comparing the pre and post jab experiences, to conclude the intensity of the spiritual life has truly diminished).
I’d rather lose 5 jobs and see my whole family sleeping in a homeless shelter than submit myself (or them) to that possible outcome.
