"No man can ever claim to have comprehended the nature of the hidden and manifold grace of God ..."

"That which thou hast heard concerning Abraham, the Friend of the All-Merciful, is the truth, and no doubt is there about it. The Voice of God commanded Him to offer up Ishmael as a sacrifice, so that His steadfastness in the Faith of God and His detachment from all else but Him may be demonstrated unto men. The purpose of God, moreover, was to sacrifice him as a ransom for the sins and iniquities of all the peoples of the earth. This same honor, Jesus, the Son of Mary, besought the one true God, exalted be His name and glory, to confer upon Him. For the same reason was Ḥusayn offered up as a sacrifice by Muḥammad, the Apostle of God.

No man can ever claim to have comprehended the nature of the hidden and manifold grace of God; none can fathom His all-embracing mercy. Such hath been the perversity of men and their transgressions, so grievous have been the trials that have afflicted the Prophets of God and their chosen ones, that all mankind deserveth to be tormented and to perish. God’s hidden and most loving providence, however, hath, through both visible and invisible agencies, protected and will continue to protect it from the penalty of its wickedness. Ponder this in thine heart, that the truth may be revealed unto thee, and be thou steadfast in His path."
