Isaiah 59:2 But your iniquities have separated between you and your God, And your sins have hid his face from you, that he will not hear.
God’s people were living in sin and rebellion. For this reason God was not answering their prayers. Their sin had caused them to walk away from and lose the blessings of God.
When I intentionally disregard and disobey what I know God wants then I can fully expect that He will not be answering my prayers. I realize that God isn’t the one that is moving away. I realize that I have made the separation not God.
I have chosen myself and my will over what God wants. I have decided that I know what is best for me. I have decided that I will do what pleases me and not God. Obviously, I will live with the consequences of that decision until I decide to honor God.
