Behind the veil is God, that God after Whom the world, with strange inconsistency, has felt, "if haply they might find Him." He has discovered Himself to some extent in nature, but more perfectly in the Incarnation; now He waits to show Himself in ravishing fulness to the humble of soul and the pure in heart.
The world is perishing for lack of the knowledge of God and the Church is famishing for want of His Presence. The instant cure of most of our religious ills would be to enter the Presence in spiritual experience, to become suddenly aware that we are in God and that God is in us. This would lift us out of our pitiful narrowness and cause our hearts to be enlarged. This would burn away the impurities from our lives as the bugs and fungi were burned away by the fire that dwelt in the bush.
What a broad world to roam in, what a sea to swim in is this God and Father of our Lord Jesus Christ. He is _eternal_, which means that He antedates time and is wholly independent of it. Time began in Him and will end in Him. To it He pays no tribute and from it He suffers no change. He is _immutable_, which means that He has never changed and can never change in any smallest measure. To change He would need to go from better to worse or from worse to better. He cannot do either, for being perfect He cannot become more perfect, and if He were to become less perfect He would be less than God. He is _omniscient_, which means that He knows in one free and effortless act all matter, all spirit, all relationships, all events. He has no past and He has no future. He _is_, and none of the limiting and qualifying terms used of creatures can apply to Him. _Love_ and _mercy_ and _righteousness_ are His, and _holiness_ so ineffable that no comparisons or figures will avail to express it. Only fire can give even a remote conception of it. In fire He appeared at the burning bush; in the pillar of fire He dwelt through all the long wilderness journey. The fire that glowed between the wings of the cherubim in the holy place was called the "shekinah," the Presence, through the years of Israel's glory, and when the Old had given place to the New, He came at Pentecost as a fiery flame and rested upon each disciple.
