“Behold, the Lord’s hand is not shortened, that it cannot save, or his ear dull, that it cannot hear; but your iniquities have made a separation between you and your God, and your sins have hidden his face from you so that he does not hear.”
Israel’s idolatry, immorality, and injustice distanced them from God.
Sin separates from God. This is the definition of spiritual death. The Bible gives one solution.
