Song Of Songs Of Solomon by Madame Guyon
6. Set me as a seal upon thy heart, as a seal upon thine arm; for love is strong as death, jealousy is cruel as hell; the lights thereof are lights of fire and flames.
The Bridegroom invites the Spouse to set Him as a seal upon her heart; for as He is the source of her life, He ought also to be its seal. It is He who hinders her from ever leaving so blessed a state; she is then the fountain sealed, which none but Himself can either open or shut. He desires also that she should set Him as a seal upon her exterior and her works, so that everything may be reserved for Him and nothing may move without His directions. She is then a garden enclosed for her Bridegroom, which He shuts and no man opens, and opens and no man shuts (Rev. iii.7). For love, says the Bridegroom, is as strong as death, to do what he pleases in His beloved. He is strong as death, inasmuch as He causes her to die to everything that she may live to Him only. But jealousy is cruel as hell, and therefore He encloses His Spouse so carefully. So strong is His desire for her utter devotion to Himself, that if we conceive her guilty of the infidelity of withdrawing her abandonment, a supposition as melancholy as it is difficult, she would be instantaneously repulsed from Him into hell by the excess of His indignation. The lamps are lamps of fire which enlighten while they burn, and consume while giving light. -- O Lamb, who openest and shuttest the seven seals! (Rev. v.5) so seal up Thy Beloved that she may no more go forth except by and for Thee; for she is Thine by an everlasting marriage.
