John 1:14
It behooves therefore those who have been deemed worthy to see and to hear such things, and who have enjoyed so great a gift, to display also a life worthy of the doctrines, that they may enjoy also the good things which are (laid up) there. For our Lord Jesus Christ came, not only that we might behold His glory here, but also that which shall be. For therefore He says, “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.
For if we shall not hereafter enjoy it, then it is time to say of ourselves, “Good were it for” us, “if” we “had never been born.” For why do we live and breathe? What are we, if we fail of that spectacle, if no one grant us then to behold our Lord? If those who see not the light of the sun endure a life more bitter than any death, what is it likely that they who are deprived of that light must suffer? For in the one case the loss is confined to this one privation; but in the other it does not rest here, (though if this were the only thing to be dreaded, even then the degrees of punishment would not be equal, but one would be as much severer than the other, as that sun is incomparably superior to this,) but now we must look also for other vengeance; for he who beholds not that light must not only be led into darkness, but must be burned continually, and waste away, and gnash his teeth, and suffer ten thousand other dreadful things.
Let us then not permit ourselves by making this brief time a time of carelessness and remissness, to fall into everlasting punishment, but let us watch and be sober, let us do all things, and make it all our business to attain to that felicity, and to keep far from that river of fire, which rushes with a loud roaring before the terrible judgment seat. For he who has once been cast in there, must remain for ever; there is no one to deliver him from his punishment, not father, not mother, not brother.
And this the prophets themselves declared aloud; one saying, “Brother delivers not brother. Shall man deliver?” And Ezekiel has declared somewhat more than this, saying, “Though Noah, Daniel, and Job were in it, they shall deliver neither sons nor daughters.” For one defense only, that through works, is there, and he who is deprived of that cannot be saved by any other means. Revolving these things, then, and reflecting upon them continually, let us cleanse our life and make it lustrous, that we may see the Lord with boldness, and obtain the promised good things; through the grace and lovingkindness of our Lord Jesus Christ, by whom and with whom, to the Father and the Holy Spirit, be glory for ever and ever. Amen.
