Isaiah 59:1 - Exposition

The Lord's hand is not shortened; i.e. God is not less able to help than of old; his "hand" has lost none of its power. That he does not help is owing to the iniquities of his people, which have separated between him and them ( Isaiah 59:2 ). It is the same fact which has made his ear heavy. He cannot hear prayers that are not sincere—not from the heart.
