One of my uncles, whom I trust and respect, let me know that my mother has confessed to him om her deathbed her profound belief in Jesus Christ as her saviour.
She has received her blessings from the country priest.
I'm not religious, but I very much understand how one could become religious. Life can be lonely, brutal, unjust and unforgiving. There is comfort and peace to be found in having God at your side.
