In Isaiah 57 God is talking to the people who believe they are “the elect” and that religion is all that is required of them. He accuses them of truly being idolaters at heart. Their only use of the divine is for their own gain and purposes. God speaks through Isaiah in 57:11 and asks: “Whom have you so dreaded and feared that you have been false to me, and have neither remembered me nor pondered this in your hearts?”
The same God that delivered the people from Egypt, through the wilderness and now from Babylon. How could they not remember all of this? How could they turn to religions and idols made with their own hands? God asks: Is it because I have been silent and you have not heard from me? Obviously this is not true as God has spoken to them many times. In reality, God has revealed all they need to know to follow him. There is no other god who has terrified them into abandoning the true God.
The truth is God asks too much!
He asks them to give up control of their lives and to live with reckless abandon in complete obedience (57:13). This is too much. They would prefer to construct and develop their own idols and religion that leaves them in control. But this is worthless in the end. God says to those with this attitude: “When you cry out for help, let your collection of idols save you.”
Are you willing to give up complete control and trust God with everything? Has God been silent in your life? If so, why do you think that is? It is surely not that he is not there. Look at the result when we give up control (last sentence of verse 13): “But the man who makes me his refuge will inherit the land and posses my holy mountain.”
He is no fool who gives what he cannot keep to gain that which he cannot lose.
