The idols of Babylon could not save themselves.
Isaiah 46:1 Bel is bowed down, Nebo bendeth; their idols are upon the beasts, and upon the cattle: the things ye carried are laid on, a burden to the weary [beast]. Isaiah 46:2 They bend, they are bowed down together; they could not deliver the burden, and themselves are gone into captivity.
God saveth his people to the end.
Isaiah 46:3 Hearken unto me, house of Jacob, and all the remnant of the house of Israel, ye who have been borne from the belly, who have been carried from the womb: Isaiah 46:4 Even to old age, I [am] HE, and unto hoary hairs I will carry [you]: It is I that have made, and I will bear, and I will carry, and will deliver.
Idols are not comparable to God for power,
Isaiah 46:5 To whom will ye liken me and make me equal, or compare me, that we may be like? Isaiah 46:6 They lavish gold out of the bag, and weigh silver in the balance; they hire a goldsmith, and he maketh it a *god: they fall down, yea, they worship. Isaiah 46:7 They bear him on the shoulder, they carry him, and set him in his place; there he standeth, he doth not remove from his place: yea, one crieth unto him, and he answereth not; he saveth him not out of his trouble. Isaiah 46:8 Remember this, and shew yourselves men; call it to mind, ye transgressors. Isaiah 46:9 Remember the former things of old; for I [am] *God, and there is none else; [I am] God, and there is none like me; Isaiah 46:10 declaring the end from the beginning, and from ancient times the things that are not yet done, saying, My counsel shall stand, and I will do all my pleasure; Isaiah 46:11 calling a bird of prey from the east, the man of my counsel from a far country. Yea, I have spoken, I will also bring it to pass; I have purposed it, I will also do it.
or present salvation.
Isaiah 46:12 Hearken unto me, ye stout-hearted, that are far from righteousness: Isaiah 46:13 I bring near my righteousness; it shall not be far off, and my salvation shall not delay; and I will give salvation in Zion, [and] unto Israel my glory.
