The aim of humanity is to become like God, to become holy, to acquire the grace of the Holy Spirit. When you come close to God and become a saint, your grace is so great that it remains in your relics even after your soul departs for death. This is why the church is nothing other than a ‘factory’ producing holy relics.
Based on St. Seraphim of Sarov, St. Silouan the Athonite
