My religion was my life, I was a man of God. I was anointed, Spirit filled, chosen and called for the work of the ministry. I loved the life. I loved the purpose it gave me. I had no desire to question it or ever leave it…Then one morning I had a stroke…[My] faith which [I] thought was unshakeable was not only shaken but eliminated entirely. As simply as flicking a light switch. The stroke cut me off from my religion, it severed the emotional and intellectual ties. I had a religious “Off” switch.
To me, this shows unequivocally that religiosity and spirituality are the products of cognitive processes, which can easily be disturbed when their neurobiological bases are damaged.
