Behold, the Lord's hand is not shortened He is not grown weaker than informer times, but is as omnipotent as ever he was; neither his ear heavy Or dull of hearing: he is not like your idol gods, that have hands and cannot help, and ears and cannot hear. But your iniquities have separated Have been as a thick wall, between you and your God And have set him at a distance from you, Proverbs 15:29. “The reason of the continuance of your calamities is not any want either of power in God to deliver you, or of goodness to hear your prayers: but your own iniquities make him a stranger to you, interrupt the correspondence that used to be between God and his people, and stop the course of his blessings.” Lowth.
