Surely the ideal way of teaching is to prove our points by constant reference to the actual words of Bahá'u'lláh and the Master. This will save the Cause from being misinterpreted by individuals. It is what these divine Lights say that is truth and therefore they should be the authorities of our statements.
(Compilations, The Compilation of Compilations vol. I, p. 215)
Divine Truth is relative and that is why we are enjoined to constantly refer the seeker to the Word itself -- and why any explanations we make to ease the journey of the soul of any individual must be based on the Word -- and the Word alone.

It is very good to memorize the logical points and the proofs of the Holy Books. Those proofs and evidences which establish the fact that Bahá'u'lláh is the fulfillment of the Promises of the Holy Books. These proofs ought to be collected and memorized. As soon as someone will ask you -- What are your proofs? -- you may cry out at the top of your voice and say: 'Here they are!'

Every word is endowed with a spirit, therefore the 173 speaker or expounder should carefully deliver his words at the appropriate time and place, for the impression which each word maketh is clearly evident and perceptible.

(Bahá'u'lláh, Tablets of Bahá'u'lláh, p. 172)
O friend of mine! The Word of God is the king of words and its pervasive influence is incalculable. It hath ever dominated and will continue to dominate the realm of being. The Great Being saith: The Word is the master key for the whole world, inasmuch as through its potency the doors of the hearts of men, which in reality are the doors of heaven, are unlocked.
(Bahá'u'lláh, Tablets of Bahá'u'lláh, p. 173)

Ye will surely exert every effort in teaching, and in furthering understanding.
