To appoint unto them that mourn in Zion, to give unto them beauty for ashes, the oil of joy for mourning, the garment of praise for the spirit of heaviness; that they might be called trees of righteousness, the planting of the Lord, that He might be glorified. – Isaiah 61:3.

Who gives this word? It is a word to mourners in Zion, meant for their consolation. But who gives it? The answer is not far to seek. It comes from Him who said, “The Spirit of the Lord God is upon Me,” “He hath sent Me to bind up the broken-hearted.” …If He declares that He will comfort us, then we may rest assured we shall be comforted! The stars in His right hand may fail to penetrate the darkness, but the rising of the Sun of Righteousness effectually scatters the gloom. If the consolation of Israel Himself comes forth for the uplifting of His downcast people, then their doubts and fears may well fly apace, since His presence is light and peace…

“The Spirit of the Lord God is upon Me; because the Lord hath appointed Me to preach good tidings unto the meek.” Remember what kind of preacher Jesus was. “Never man spake like this man.” He was a Son of consolation indeed. It was said of Him, “A bruised reed shall He not break, and the smoking flax shall He not quench.” He was gentleness itself…Now, if such be the person who declares He will comfort the broken-hearted, if He be such a preacher, we may rest assured He will accomplish His work.~ C.H.
