Verily the Son is in the Father, and the Father is in the Son.

                                                                                                                                                                                                                                                                                                                                                                                                                                                            Know thou that the Divine Essence, which is called the Invisible of the Invisibles, never to be described, beyond the reach of mind — is sanctified above any mention, any definition or hint or allusion, any acclamation or praise. In the sense that It is that It is, the intellect can never grasp It, and the soul seeking knowledge of It is but a wanderer in the desert, and far astray. ‘No vision taketh in Him, but He taketh in all vision: He is the Subtile, the All-Informed.’ [1]
[1 Qur’án 6:103]

When, however, thou dost contemplate the innermost essence of all things, and the individuality of each, thou wilt behold the signs of thy Lord’s mercy in every created thing, and see the spreading rays of His Names and Attributes throughout all the realm of being, with evidences which none will deny save the froward and the unaware. Then wilt thou observe that the universe is a scroll that discloseth His hidden secrets, which are preserved in the well-guarded Tablet. And not an atom of all the atoms in existence, not a creature from amongst the creatures but speaketh His praise and telleth of His attributes and names, revealeth the glory of His might and guideth to His oneness and His mercy: and none will gainsay this who hath ears to hear, eyes to see, and a mind that is sound.

And whensoever thou dost gaze upon creation all entire, and dost observe the very atoms thereof, thou wilt note that the rays of the Sun of Truth are shed upon all things and shining within them, and telling of that Day-Star’s splendours, Its mysteries, and the spreading of Its lights. Look thou upon the trees, upon the blossoms and fruits, even upon the stones. Here too wilt thou behold the Sun’s rays shed upon them, clearly visible within them, and manifested by them.

Shouldst thou, however, turn thy gaze unto a Mirror, brilliant, stainless, and pure, wherein the divine Beauty is reflected, therein wilt thou find the Sun shining with Its rays, Its heat, Its disc, Its fair form all entire. For each separate entity possesseth its allotted portion of the solar light and telleth of the Sun, but that Universal Reality in all Its splendour, that stainless Mirror Whose qualities are appropriate to the qualities of the Sun revealed within It — expresseth in their entirety the attributes of the Source of Glory. And that Universal Reality is Man, the divine Being, the Essence that abideth forever. ‘Say, Call upon God, or call upon the All-Merciful; whichsoever ye call upon, most beauteous are His Names.’ [1]
[1 Qur’án 17:110]

This is the meaning of the Messiah’s words, that the Father is in the Son. [1] Dost thou not see that should a stainless mirror proclaim, ‘Verily is the sun ashine within me, together with all its qualities, tokens and signs’, such an utterance by such a mirror would be neither deceptive nor false? No, by the One Who created It, shaped It, fashioned It, and made It to be an entity conformable to the attributes of the glory within It! Praised be He Who created It! Praised be He Who fashioned It! Praised be He Who made It manifest!
[1 John 14:11]

Such were the words uttered by Christ. On account of these words they cavilled at and assailed Him when He said unto them, ‘Verily the Son is in the Father, and the Father is in the Son.'[1] Be thou informed of this, and learn thou the secrets of thy Lord. As for the deniers, they are veiled from God: they see not, they hear not, neither do they understand. ‘Leave them to entertain themselves with their cavillings.’ [2] Abandon them to their wanderings along river beds where no stream flows. Like grazing beasts they cannot tell paste from pearl. Are they not shut away from the mysteries of thy Lord, the Clement, the Merciful?
[1.John 14:10]
[2 Qur’án 6:91]

For thy part, rejoice at this best of all glad tidings, and rise up to exalt the Word of God and to spread abroad His sweet savours in all that vast and mighty land. Know thou of a certainty that thy Lord will come to thine aid with a company of the Concourse on high and hosts of the Abhá Kingdom. These will mount the attack, and will furiously assail the forces of the ignorant, the blind. Erelong wilt thou behold the flush of daybreak spreading from out the Most Exalted Realm, and the morn encompassing all regions. It will put the dark to flight, and the gloom of night will fade and pass, and the bright brow of the Faith shine forth, and the Day-Star rise and overspread the world. On that day will the faithful rejoice, and the steadfast be blissful; then will the slanderers take themselves off, and the waverers be blotted out, even as deepest shadows fall away at the first light of the breaking dawn.

Greetings be unto thee, and praise.
