Why should we be Confident in God?

God sent his Servant to personally establish his righteousness among the nations (Isa 42:1-7), distinguishing himself over idols (Isa 42:8-9), that we would praise him for his zealous victory (Isa 42: 10-13).

Isa 42:5-8 ESV

⁵ Thus says God, the Lord,
    who created the heavens and stretched them out,
    who spread out the earth and what comes from it,
who gives breath to the people on it
    and spirit to those who walk in it:
⁶ “I am the Lord; I have called you in righteousness;
    I will take you by the hand and keep you;
I will give you as a covenant for the people,
    a light for the nations,
⁷     to open the eyes that are blind,
to bring out the prisoners from the dungeon,
    from the prison those who sit in darkness.
⁸ I am the Lord; that is my name;
    my glory I give to no other,
    nor my praise to carved idols.
