Charles H. Spurgeon on Psalms 1:3

"And whatsoever he doeth, [or, maketh or taketh in hand] shall prosper." And with regard to this "prospering," take heed that thou understandest not a carnal prosperity. This prosperity is hidden prosperity, and lies entirely secret in spirit; and therefore if thou hast not this prosperity that is by faith, thou shouldest rather judge thy prosperity to be the greatest adversity. For as the devil bitterly hates this leaf and the word of God, so does he also those who teach and hear it, and he persecutes such, aided by all the powers of the world. Therefore thou hearest of a miracle the greatest of all miracles, when thou hearest that all things prosper which a blessed man doeth. Martin Luther.
