“Say to them that are of a fearful heart: be strong, fear not, behold your God.”

"And likewise, He saith: “Say to them that are of a fearful heart: be strong, fear not, behold your God.” This blessed verse is a proof of the greatness of the Revelation, and of the greatness of the Cause, inasmuch as the blast of the trumpet must needs spread confusion throughout the world, and fear and trembling amongst all men. Well is it with him who hath been illumined with the light of trust and detachment. The tribulations of that Day will not hinder or alarm him. Thus hath the Tongue of Utterance spoken, as bidden by Him Who is the All-Merciful. He, verily, is the Strong, the All-Powerful, the All-Subduing, the Almighty. It is now incumbent upon them who are endowed with a hearing ear and a seeing eye to ponder these sublime words, in each of which the oceans of inner meaning and explanation are hidden, that haply the words uttered by Him Who is the Lord of Revelation may enable His servants to attain, with the utmost joy and radiance, unto the Supreme Goal and Most Sublime Summit—the dawning-place of this Voice."
