The happiness God promises certainly knows no limits. When one has gained such a blessing, what is left to desire? In seeing God one possesses all things. In the language of Scripture, to see is to have. May you see the good things of Jerusalem is the same as May you possess the good things of Jerusalem. When the prophet says: May the wicked man be carried off and not see the glory of the Lord, he means: May he not share in the glory of the Lord. One who has seen God has, in the act of seeing, gained all that is counted good: life without end, everlasting freedom from decay, undying happiness, a kingdom that has no end, lasting joy, true light, a voice to sing pleasingly in the spirit, unapproachable glory, perpetual rejoicing, in a word, the totality of blessing. Such is the wonderful hope held out by the beatitudes. As we have seen, the condition for seeing God is purity of heart, and now once more my mind is in confusion, as from an attack of giddiness, wondering if purity of heart is something impossible, something beyond the capacity of human nature. If the vision of God is dependent on purity of heart, and if Moses and Paul did not attain this vision—they state that neither they nor anyone else can see God—then the promise of the beatitude spoken by the Word seems to be something impossible of realization.
