How can the church make the believer “a high mountain” that soars in the heavens above all worldly matters?

St. Augustine says “The mountain resembles the soul that elevates herself above that which is temporal, to soar in the heavens. The holy city of God that cannot be hidden is set on this mountain, so that the holy church is adorned in the lives of the saints. On this holy mountain, the Lord Himself ascends to converse with His people, so that the mountain can be a true witness to Him, through one’s holy life.”
