Behold, the Lord’s hand is not shortened, that it cannot save; neither His ear heavy, that it cannot hear:
2 But your iniquities have separated between you and your God, and your sins have hid His face from you, that He will not hear.
I remember someone saying, years ago, that when we feel far from God, He is not the One Who moved!
God is Who He always has been. Here, He is telling Israel that it is their own iniquities that have separated them from God; it is their own sin that He cannot look upon; and when we are in sin, He will not hear our prayers.
Why do we so often ask, “How could a loving God allow/not protect/not save me from this terrible trouble?” The answer is in these two verses. We simply don’t want to hear it. We want God to always intervene, no matter how distant from Him we have become.
