This is a contrast between God, the true and the living eternal God that created the heavens and the earth, and the false gods that the Israelites were worshipping. This chapter reads about the salvation of the Israel of God, the spiritual Israel, chosen, redeemed, and called, and who shall be saved with everlasting salvation. Reads about the glory of God, the grace of God, and the righteousness of God upon them, by which they are glorious. It is like God rescued us from sin and has been with us through it all. God sustains us in our faith all the moments, days, and years of our lives. God will never leave nor forsake us. Like it reads in Deuteronomy 31:6.
It reads in Isaiah 46:1-13 KJV> Bel boweth down, Nebo stoopeth, their idols were upon the beasts, and upon the cattle: your carriages were heavy loaden; they are a burden to the weary beast. They stoop, they bow down together; they could not deliver the burden, but themselves are gone into captivity. Hearken unto me, O house of Jacob, and all the remnant of the house of Israel, which are borne by me from the belly, which are carried from the womb: And even to your old age I am he; and even to hoar hairs will I carry you: I have made, and I will bear; even I will carry, and will deliver you. To whom will ye liken me, and make me equal, and compare me, that we may be like? 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, yea, they worship. 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: yea, one shall cry unto him, yet can he not answer, nor save him out of his trouble. Remember this, and shew yourselves men: bring it again to mind, O ye transgressors. Remember the former things of old: for I am God, and there is none else; I am God, and there is none like me, 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: Calling a ravenous bird from the east, the man that executeth my counsel from a far country: yea, I have spoken it, I will also bring it to pass; I have purposed it, I will also do it. Hearken unto me, ye stouthearted, that are far from righteousness: I bring near my righteousness; it shall not be far off, and my salvation shall not tarry: and I will place salvation in Zion for Israel my glory.
