Macarius of Egypt

If indeed the soul takes refuge in God, believes and seeks the salt of life which is the good and person-loving Spirit, then the heavenly salt comes and kills those ugly worms. The Spirit takes away the awful stench and cleanses the soul by the strength of his salt. Thus the soul is brought back to health and freed from its wounds by the true salt in order to be again useful and ordered to serve the heavenly Lord. That is why even in the law God uses this example when he ordered that all sacrifices be salted with salt.
