The idols of Babylon could not save themselves.
Isaiah 46:1 Bel boweth down, Nebo stoopeth, their idols were upon the beasts, and upon the cattle: your loads [were] heavy; [they were] a burden to the weary [beast]. Isaiah 46:2 They stoop, they bow down together; they could not deliver the burden, but themselves have gone into captivity.
God saveth his people to the end.
Isaiah 46:3 Hearken to me, O house of Jacob, and all the remnant of the house of Israel, which are borne [by me] from the birth, which are carried from the womb: Isaiah 46:4 And [even] to [your] old age I [am] he; and [even] to hoary hairs will I carry [you]: I have made, and I will bear; even I will carry, and will deliver [you].
Idols are not comparable to God for power,
Isaiah 46:5 To whom will ye liken me, and make [me] equal, and compare me, that we may be like? Isaiah 46:6 They lavish gold out of the bag, and weigh silver in the balance, [and] hire a goldsmith; and he maketh it a god: they fall down, yes, they worship. Isaiah 46:7 They bear him upon the shoulder, they carry him, and set him in his place, and he standeth; from his place shall he not remove: yes, [one] shall cry to him, yet he cannot answer, nor save him out of his trouble. Isaiah 46:8 Remember this, and show yourselves men: bring [it] again to mind, O 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 ravenous bird from the east, the man that executeth my counsel from a far country: yes, I have spoken [it], I will also bring it to pass; I have purposed [it], I will also perform it.
or present salvation.
Isaiah 46:12 Hearken to 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 place salvation in Zion for Israel my glory.
