As to thy question concerning the husband and wife, the tie
between them and the children given to them by God: Know thou, verily, the
husband is one who hath sincerely turned unto God, is awakened by the call of
the Beauty of El-Bahá and chanteth the verses of Oneness in the great
assemblies; the wife is a being who wisheth to be overflowing with and seeketh
after the attributes of God and His names; and the tie between them is none
other than the Word of God. Verily, it [the Word of God] causeth the multitudes
to assemble together and the remote ones to be united. Thus the husband and
wife are brought into affinity, are united and harmonized, even as though they
were one person. Through their mutual union, companionship and love great
results are produced in the world, both material and spiritual. The spiritual
result is the appearance of divine bounties. The material result is the
children who are born in the cradle of the love of God, who are nurtured by the
breast of the knowledge of God, who are brought up in the bosom of the gift of
God, and who are fostered in the lap of the training of God. Such children are
those of whom it was said by Christ, "Verily, they are the children of the
Kingdom!"
