“Tell us, you idols, what is going to happen. Tell us what the former things were, so that we may consider them and know their final outcome. Or declare to us the things to come, tell us what the future holds, so we may know that you are gods" (Isa 41:22-23a).
Theme: An idol is anything that you like and depend on more than God. Idolatry is every man's default. Fear leads to the making and depending on idols who can never save us. The proof that God and God alone is Lord of the historical process is that he announces beforehad what will happen, and then brings it to pass, which is something that an idol can never do.
In 41:21-29 God/Isaiah present their case against the idols. This occurs 5 times between ch. 41 to 46.
