  But while the light is undoubtedly divine or supernatural in nature, according to Fell, it is still up to the individual to direct her mind to the light in order to attain redemption. Above all, personal salvation depends upon the mind discerning the light within and then diligently keeping to it. The individual must engage in constant mental effort, she must “consider seriously” and “come to search and examine” her beliefs for herself (Fell 1656b, 1, 14).
