The fire of God is experienced differently for the wicked than the righteous

In the flame of fire the Lord will judge the wicked.  But the fire shall not touch the just, but shall by all means lick them up.  In one place they delay, but a part has wept at the judgment.  Such will be the heat, that the stones themselves shall melt.  The winds assemble into lightnings, the heavenly wrath rages; and wherever the wicked man fleeth, he is seized upon by this fire.  There will be no succour nor ship of he sea.  Amen, flames on the nations, and the Medes and Parthians burn for a thousand years, as the hidden words of John declare.  For then after a thousand years they are delivered over to Gehenna; and he whose work they were, with them are burnt up.

Chapter XLIII

The soul lives on — death is not an escape from God

O fool, thou dost not absolutely die; nor, when dead, dost thou escape the lofty One.  Although thou shouldst arrange that when dead thou perceivest nothing, thou shalt foolishly be overcome.  God the Creator of the world liveth, whose laws cry out that the dead are in existence.  But thou, whilst recklessly thou seekest to live without God, judgest that in death is extinction, and thinkest that it is absolute.  God has not ordered it as thou thinkest, that the dead are forgetful of what they have previously done.  Now has the governor made for us receptacles of death, and after our ashes we shall behold them.  Thou art stripped, O foolish one, who thinkest that by death thou art not, and hast made thy Ruler and Lord to be able to do nothing.  But death is not a mere vacuity, if thou reconsiderest in thine heart.  Thou mayest know that He is to be desired, for late thou shalt perceive Him.  Thou wast the ruler of the flesh; certainly flesh ruled not thee.  Freed from it, the former is buried; thou art here.  Rightly is mortal man separated from the flesh.  Therefore mortal eyes will not be able to be equalled (to divine things).  Thus our depth keeps us from the secret of God.  Give thou now, whilst in weakness thou art dying, the honour to God, and believe that Christ will bring thee back living from the dead.  Thou oughtest to give praises in the church to the omnipotent One.

Chapter XXVII

Faith in Christ overcomes the “second death” after the resurrection

Now astounded, swear that thou wilt believe in Christ; for the Old Testament proclaims concerning Him.  For it is needful only to believe in Him who was dead, to be able to rise again to live for all time.  Therefore, if thou art one who disbelievest that these things shall be, at length he shall be overcome in his guilt in the second death.  I will declare things to come in few words in this little treatise.  In it can be known when hope must be preferred.  Still I exhort you as quickly as possible to believe in Christ.

Chapter XXV

Reward and punishment begin before the resurrection

And, moreover, thou sayest, Who is He who has redeemed from death, that we may believe in Him, since there punishments are awarded?  Ah! not thus, O malignant man, shall it be as thou thinkest.  For to him who has lived well there is advantage after death.  Thou, however, when one day thou diest, shalt be taken away in an evil place.  But they who believe in Christ shall be led into a good place, and those to whom that delight is given are caressed; but to you who are of a double mind, against you is punishment without the body.

Chapter XXIV

The body will be raised just as the trees return to bloom in spring

Every body, whether it is dried up into dust, or is dissolved into moisture, or is compressed into ashes, or is attenuated into smoke, is withdrawn from us, but it is reserved for God in the custody of the elements.  Nor, as you believe, do we fear any loss from sepulture, but we adopt the ancient and better custom of burying in the earth.  See, therefore, how for our consolation all nature suggests a future resurrection.  The sun sinks down and arises, the stars pass away and return, the flowers die and revive again, after their wintry decay the shrubs resume their leaves, seeds do not flourish again. unless they are rotted: thus the body in the sepulchre is like the trees which in winter hide their verdure with a deceptive dryness.  Why are you in haste for it to revive and return, while the winter is still raw?  We must wait also for the spring-time of the body.  And I am not ignorant that many, in the consciousness of what they deserve, rather desire than believe that they shall be nothing after death; for they would prefer to be altogether extinguished, rather than to be restored for the purpose of punishment.  And their error also is enhanced, both by the liberty granted them in this life, and by God’s very great patience, whose judgment, the more tardy it is, is so much the more just.

God is everywhere present and fills all things

Thou errest, O man, and art deceived; for from where is God afar off, when all things heavenly and earthly, and which are beyond this province of the universe, are known to God, are full of God?  Everywhere He is not only very near to us, but He is infused into us. Therefore once more look upon the sun:  it is fixed fast in the heaven, yet it is diffused over all lands equally; present everywhere, it is associated and mingled with all things; its brightness is never violated.  How much more God, who has made all things, and looks upon all things, from whom there can be nothing secret, is present in the darkness, is present in our thoughts, as if in the deep darkness.  Not only do we act in Him, but also, I had almost said, we live with Him.
