Isaiah 26:10

In this human form the good will see him in whom they have believed; the wicked, him whom they have despised. But the wicked will not see him in the form of God in which he is equal to the Father, for as the prophet says, "The wicked shall be taken off that he may not see the glory of the Lord," and, on the other hand, "Blessed are the clean of heart, for they shall see God."

Then, therefore, we shall come and we shall enjoy the one thing; but the one thing will be all things to us. For what was it I said, my brothers, when I began to speak? What is that sufficiency which we shall possess when we shall have no need? What is the sufficiency which we shall possess? I had intended to say, "What will God give to us which he will not give to them?" "Let the wicked be taken away that he may not see the glory of God." Hence God will give his glory to us so that we may enjoy it; and the wicked will be taken away that he may not see the glory of God. God himself will be the entire sufficiency which we shall possess as our own. Greedy one, what did you seek to gain? What does anyone, for whom God is not enough, seek from God?

In the resurrection itself it is not easy to see God, except for those who are clean of heart; hence, "Blessed are the clean of heart, for they shall see God." From here on he begins to speak of that world where all who rise again will not see God, but only those who rise to eternal life. The unworthy will not see him, for of them it is said, "Let the wicked be taken away lest he behold the brightness of the Lord." But the worthy will see him, and of such the Lord spoke when, though present, he was not seen, saying, "He that loves me keeps my commandments, and he that loves me shall be loved of my Father, and I will love him and will manifest myself to him."

(Verse 10.) When you execute your judgments on the earth, the inhabitants of the world will learn righteousness. Show mercy to the wicked, who does not learn righteousness; in the land of the saints he acts unjustly and does not see the glory of the Lord. Learn righteousness, you who dwell on the earth. The wicked will cease to exist and will not learn righteousness on the earth; he will not act with truth, let the wicked be taken away so he will not see the glory of the Lord. Let us first speak according to the Hebrew, and if we want to express the meaning of the prophet, then let us turn to the Septuagint Interpreters. As long as you do not exercise your judgments upon the earth, and neither reward the good with good nor the evil with evil, your justice, O Lord God, is ignored on earth. But when on the day of judgment you will render to each according to the quality of their deeds, then your justice will be known throughout the world, which previously seemed unjust among the unbelievers, so that even one of the saints would say: My steps were nearly weakened, my feet were nearly poured out, for I was zealous for the wicked, seeing the peace of the sinners (Ps. LXXII, 2). To which the Lord responded: Let us have mercy on the wicked; for except for the Seventy, all others have also translated it this way. And the meaning is: may the wicked obtain mercy even more, and may he learn my clemency; so that he himself may also be saved. And in response to the Lord speaking, the Prophet, representing human impatience, replied: And he will not learn justice. And the meaning is: and how will he be able to know your justice if he has only experienced your clemency? And the reasons why he wants to learn the justice of God are as follows: because he acted unjustly on the earth of the saints, and continually fought against your saints, he must feel torment. […]

For our Lord Jesus Christ came, not only that we might behold His glory here, but also that which shall be. For therefore He saith, "I will that these also be with Me where I am, that they may behold My glory." Now if the glory here was so bright and splendid, what can one say of that which shall be? for it shall appear not on this corruptible earth, nor while we are in perishable bodies, but in a creation which is imperishable, and waxes not old, and with such brightness as it is not possible even to represent in words. O blessed, thrice blessed, yea many times so, they who are deemed worthy to be beholders of that glory! It is concerning this that the prophet says, "Let the unrighteous be taken away, that he behold not the glory of the Lord." God grant that not one of us be taken away nor excluded ever from beholding it.
