Indeed, is He not known through this also as God by nature? To whom else can the power belong to give life forever to those who hear the words from Him, if not to God by nature?
The divine word is kept when one does not transgress the divine commandment. One must constantly and exactly fulfill what has been ordained, and in no way become subject to the charge of neglecting the divine laws.
Notice again the precision of this saying. He did not allow Himself to say, "If anyone hears My word," but, "If anyone keeps My word." For not only people guilty of sin receive the word of God by hearing, but also the impious multitude of demons.
Thus Satan, the leader of all demons, dared to tempt our Lord Jesus Christ in the wilderness. Because of the great savagery of his character, he kicked against the goads and presented the divine word to Him.
He said, "It is written that He shall give His angels charge over You, to keep You in all Your ways" (Lk 4:10; Ps 90:11).
Therefore the word of salvation is not in mere hearing. Life is not in teaching alone. It is in keeping what has been heard, and in making the divine word the rule and guide of life.
When He says that the firm guardian of His words "shall never see death," He certainly does not abolish the death of the flesh. Rather, as God, He does not regard death as death.
For nothing is dead to Him, since He brings even what does not exist into being. He easily gives life to what has fallen into corruption.
Or He says that the saints will not see death in the age to come. That age alone should properly be regarded as the true age, since it has no end, unlike this age of ours.
When He says that those who keep His divine teaching will not see death in that age, He does not mean that some may die after the resurrection. The death of all has been destroyed by the death of Christ. The power of corruption has vanished.
Rather, with perfect justice He calls eternal punishment death. You may be convinced of this by considering His earlier words: "Truly I say to you, he who believes in the Son has eternal life, but he who does not believe the Son shall not see life" (Jn 3:36).
Yet all will be made alive and will enter Life again, both believers and unbelievers. The resurrection is by no means partial. It is common to all in this respect, that all will live again.
How, then, shall the one who does not believe the Son not see life, although we expect the resurrection of all? Everyone surely knows that Christ is accustomed to call life the eternal living in blessedness and glory that knows no end.
This life is kept in hope for the saints. When He says that the one who does not obey the Son will not see life, although all await being made alive, He does not indicate the life of the body.
He calls life the blessedness prepared for the saints. In the same way, I think, He says that the noble and manly guardian of His divine words shall never see death.
By this He clearly does not mean the death of the body, but the punishment prepared for sinners. As in that saying blessedness is indicated by the word "life," so here punishment is indicated by the word "death."
