Again, in John Chrysostom's commentary on the Acts, we see a progression of holiness, the calling of the Apostles to fast, pray, watch for the coming of the Holy Spirit. What better way to describe the Dark Night of the Soul than this waiting, this preparing for Christ?
For it cannot, it cannot be,
      that a man should enjoy the benefit of grace except he watch. Seest
      thou not what Elias saith to his disciple? “If thou see me when I
      am taken up” (2 Kings ii. 10),
      this that thou askest shall be done for thee. Christ also was ever wont
      to say unto those that came unto Him, “Believest thou?” For
      if we be not appropriated and made over to the thing given,20 neither do we greatly feel the benefit. So it
      was also in the case of Paul; grace did not come to him immediately,
      but three days intervened, during which he was blind; purified the
      while, and prepared by fear. For as those who dye the purple first
      season with other ingredients the cloth that is to receive the dye,
      that the bloom may not be fleeting;21 so in this
      instance God first takes order that the soul shall be thoroughly in
      earnest, and then pours forth His grace. On this account also, neither
      did He immediately send the Spirit, but on the fiftieth day. Now if any
      one ask, why we also do not baptize at that season of Pentecost? we may
      answer, that grace is the same now as then;22 but
      the mind becomes more elevated now, by being prepared through fasting.
      And the season too of Pentecost furnishes a not unlikely reason. What
      may that be? Our fathers held Baptism 8to be just the proper curb upon
      evil concupiscence, and a powerful lesson for teaching to be
      sober-minded even in a time of delights.
   
   
As if then we were banquetting
      with Christ Himself, and partaking of His table, let us do nothing at
      random, but let us pass our time in fastings, and prayers, and much
      sobriety of mind. For if a man who is destined to enter upon some
      temporal government, prepares himself all his life long, and that he
      may obtain some dignity, lays out his money, spends his time, and
      submits to endless troubles; what shall we deserve, who draw near to
      the kingdom of heaven with such negligence, and both show no
      earnestness before we have received, and after having received are
      again negligent? Nay, this is the very reason why we are negligent
      after having received, that we did not watch before we had received.
      Therefore many, after they have received, immediately have returned to
      their former vomit, and have become more wicked, and drawn upon
      themselves a more severe punishment; when having been delivered from
      their former sins, herein they have more grievously provoked the Judge,
      that having been delivered from so great a disease, still they did not
      learn sobriety, but that has happened unto them, which Christ
      threatened to the paralytic man, saying, “Behold thou art made
      whole: sin no more, lest a worse thing come unto thee”
      (John v. 14): and which He also predicted of the Jews, that “the last
      state shall be worse than the first.” (Matt. xii. 45.) For if,
      saith He, showing that by their ingratitude they should bring upon them
      the worst of evils, “if I had not come, and spoken unto them,
      they had not had sin” (John xv. 22); so that the
      guilt of sins committed after these benefits is doubled and quadrupled,
      in that, after the honour put upon us, we show ourselves ungrateful and
      wicked. And the Laver of Baptism helps not a whit to procure for us a
      milder punishment. And consider: a man has gotten grievous sins by
      committing murder or adultery, or some other crime: these were
      remitted through Baptism. For there is no sin, no impiety, which does
      not yield and give place to this gift; for the Grace is Divine. A man
      has again committed adultery and murder; the former adultery is indeed
      done away, the murder forgiven, and not brought up again to his charge,
      “for the gifts and calling of God are without repentance”
      (Rom. xi. 29); but for those committed after Baptism he suffers a punishment
      as great as he would if both the former sins were brought up again, and
      many worse than these. For the guilt is no longer simply equal, but
      doubled and tripled.23 Look: in proof that
      the penalty of these sins is greater, hear what St. Paul says:
      “He that despised Moses’ law died without mercy, under two
      or three witnesses: of how much sorer punishment, suppose ye, shall he
      be thought worthy, who hath trodden under foot the Son of God, and hath
      counted the blood of the covenant an unholy thing, and hath done
      despite unto the Spirit of grace?” (Heb. x. 28, 29.)
