“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, I will also bring it to pass; I have purposed, I will also do it.” Isaiah 46:9-11 (KJB)

God has spoken, and every word He has spoken shall come to pass just as He has said.  He has purposed, and every purpose will be done.

From F. B. Meyer

“Here is a startling contrast! Babylon is broken up. An invading army of stern monotheists have slain the idolatrous priests at their altars and are engaged in carrying out the idols for the bonfire. And as the Jewish remnant is witnessing the extraordinary spectacle, they are reminded that their God does not require to be borne. Nay, on the contrary He has borne His people from the earliest days and will continue to bear them till the heavens have passed away.

The contrast is a perpetual one. Some people carry their religion; others are carried by it. Some are burdened by minute prescriptions and an external ritual; others yield themselves to God, to be borne by Him in old age as they were in the helplessness of childhood. They are persuaded that He will bear them “as a man doth bear His son,” in all the way that they go, until they come to the prepared place. See Deu_1:31; Isa_63:9. God immediately responds to a trust like that, and His salvation does not tarry.”  From Through the Bible Day by Day – F. B. Meyer on Isaiah 46:1-13

What He has spoken concerning His Son Jesus will come to pass.  What He has purposed concerning you and me will be done.
