Baha'u'llah has answered your question;
"...He is indeed as one dead who, at the wondrous dawn of this Revelation, hath failed to be quickened by its soul-stirring breeze. He is indeed a captive who hath not recognized the Supreme Redeemer, but hath suffered his soul to be bound, distressed and helpless, in the fetters of his desires. O My servants! Whoso hath tasted of this Fountain hath attained unto everlasting Life, and whoso hath refused to drink therefrom is even as the dead..."
Baha'u'llah : Gleanings from the Writings of Baha'u'llah
Yes each day the Dead Bury more Dead. But yes it is the Spiritually Dead that do this. Flesh is not Life.
Baha'u'llah has provided the answer to this as well;
"...Incline your ears to the sweet melody of this Prisoner. Arise, and lift up your voices, that haply they that are fast asleep may be awakened. Say: O ye who are as dead! The Hand of Divine bounty proffereth unto you the Water of Life. Hasten and drink your fill. Whoso hath been re-born in this Day, shall never die; whoso remaineth dead, shall never live."

Jesus Christ the Son has returned as the Father, life is now found in the Father, rejection of the Father is Death, Baha'u'llah again has supplied your answer;
"..The Word which the Son concealed is made manifest. It hath been sent down in the form of the human temple in this day. Blessed be the Lord Who is the Father! He, verily, is come unto the nations in His most great majesty. Turn your faces towards Him, O concourse of the righteous... This is the day whereon the Rock (Peter) crieth out and shouteth, and celebrateth the praise of its Lord, the All-Possessing, the Most High, saying: 'Lo! The Father is come, and that which ye were promised in the Kingdom is fulfilled!...' My body longeth for the cross, and Mine head waiteth the thrust of the spear, in the path of the All-Merciful, that the world may be purged from its transgressions...."
Baha'u'llah : The Proclamation of Baha'u'llah
This is the day promised by Christ. Life is now found in the Father. Baha'u'llah has again explained this in great detail, here is but one passage;
"...Such things have come to pass in the days of every Manifestation of God. Even as Jesus said: "Ye must be born again." [John 3:7] Again He saith: "Except a man be born of water and of the Spirit, he cannot enter into the Kingdom of God. That which is born of the flesh is flesh; and that which is born of the Spirit is spirit." [John 3:5-6]. The purport of these words is that whosoever in every dispensation is born of the Spirit and is quickened by the breath of the Manifestation of Holiness, he verily is of those that have attained unto "life" and "resurrection" and have entered into the "paradise" of the love of God. And whosoever is not of them, is condemned to "death" and "deprivation," to the "fire" of unbelief, and to the "wrath" of God. In all the scriptures, the books and chronicles, the sentence of death, of fire, of blindness, of want of understanding and hearing, hath been pronounced against those whose lips have tasted not the ethereal cup of true knowledge, and whose hearts have been deprived of the grace of the holy Spirit in their day. Even as it hath been previously recorded: "Hearts have they with which they understand not" [Qur'an 7:178].
.
In another passage of the Gospel it is written: "And it came to pass that on a certain day the father of one of the disciples of Jesus had died. That disciple reporting the death of his father unto Jesus, asked for leave to go and bury him. Whereupon, Jesus, that Essence of Detachment, answered and said: "Let the dead bury their dead." [Luke 9:60]
.
In like manner, two of the people of Kufih went to Ali, the Commander of the Faithful. One owned a house and wished to sell it; the other was to be the purchaser. They had agreed that this transaction should be effected and the contract be written with the knowledge of Ali. He, the exponent of the law of God, addressing the scribe, said: "Write thou: 'A dead man hath bought from another dead man a house. That house is bounded by four limits. One extendeth toward the tomb, the other to the vault of the grave, the third to the Sirat, the fourth to either Paradise or hell.'" Reflect, had these two souls been quickened by the trumpet-call of Ali, had they risen from the grave of error by the power of his love, the judgment of death would certainly not have been pronounced against them.
In every age and century, the purpose of the Prophets of God and their chosen ones hath been no other but to affirm the spiritual significance of the terms "life," "resurrection," and "judgment." If one will ponder but for a while this utterance of Ali in his heart, one will surely discover all mysteries hidden in the terms "grave," "tomb," "sirat," "paradise" and "hell." But oh! how strange and pitiful! Behold, all the people are imprisoned within the tomb of self, and lie buried beneath the nethermost depths of worldly desire! Wert thou to attain to but a dewdrop of the crystal waters of divine knowledge, thou wouldst readily realize that true life is not the life of the flesh but the life of the spirit. For the life of the flesh is common to both men and animals, whereas the life of the spirit is possessed only by the pure in heart who have quaffed from the ocean of faith and partaken of the fruit of certitude. This life knoweth no death, and this existence is crowned by immortality. Even as it hath been said: "He who is a true believer liveth both in this world and in the world to come." If by "life" be meant this earthly life, it is evident that death must needs overtake it.
