Isaiah 55:9

"For as the heavens are higher than the earth, so are my ways higher than your ways, and my thoughts than your thoughts. For as the rain cometh down and the snow from heaven, and returneth not thither, but watereth the earth, and maketh it bring forth and bud, and giveth seed to the sower, and bread to the eater; so shall my word be that goeth forth out of my mouth: it shall not return unto me void, but it shall accomplish that which I please, and it shall prosper in the thing whereto I sent it."

This is one of the most remarkable passages in the word of God, especially the declaration that God's Word will always accomplish the thing whereto God sent it. This is exactly the thing Paul referred to when he said, "The gospel is a savor (an odor) of life unto life in them that are saved and an odor of death unto death in them that perish" (2 Corinthians 2:15-17).

Paul's wonderful metaphor here is derived from the custom of the Roman Triumphal Processions in which tremendous quantities of incense were burned along the parade route. Those destined to die in the arena, following the triumph, and those to be released by the clemency of the triumphal Emperor, naturally viewed the tremendous odors of the day in different lights. For other interesting studies on this see Vol. 7 (1,2Corinthians) in my New Testament Series of Commentaries, pp. 324-326.

Yes, God's Word will either destroy the persons who hear it and do not obey it, or it will redeem the ones who receive it and obey it. The utmost caution, therefore, should be exercised in the study o f the Word of God. Just as the same sunshine will melt butter or harden putty, the same glorious gospel of Christ will either redeem or condemn them that hear it.
