Do you ever doubt God? Be sure you have the right 'god' in mind. God by definition as the one true God will be there to bless you. In the Old Testament, God helped Israel as a people see that he was the true God because he actually answered prayers in his way. Thus, from God's view, an idol by definition cannot move to help, or hear, Isaiah 46. God states plainly (and He would know): "for I am God, and there is no other; I am God, and there is none like me." This is right after having said that alternative 'gods' of the people of the earth do not truly exist because they are unable to deliver.
Today you should walk in the promise when you read this, God's promise: "My counsel shall stand, and I will accomplish all my purpose." (emphasis mine) The way to remember this is to remember what happened to those who sinned (Isaiah 46:3, 8, 10, 11b). This will help you when you feel the tendency to wander off from righteous living to return to God, and know that He alone can deliver you. Then going forward, the God who does ALL of his purpose will bless you who are His people through faith in Jesus.
