How do we know we are instructed by God to commit an act? What is the proof that the spiritual feelings and sensations we experience isn’t all in our head? In essence, Charles Manson and many other men thought what they were doing was right and may even have believed that they were told by God to commit these acts, does this ever occur and how can it be legitimized and trusted? ( My friends are quarrelsome, but hopefully a direct answer will help at least open their minds to the Gospel)
