Passage
Yea, before the day was I am he; and there is none that can deliver out of my hand: I will work, and who shall let it?
Yea, before the day was I am he; and there is none that can deliver out of my hand: I will work, and who shall let it?
Isaiah 43:11 I, even I, am the LORD; and beside me there is no saviour.
Isaiah 43:12 I have declared, and have saved, and I have shewed, when there was no strange god among you: therefore ye are my witnesses, saith the LORD, that I am God.
Isaiah 43:13 Yea, before the day was I am he; and there is none that can deliver out of my hand: I will work, and who shall let it?
Isaiah 43:14 Thus saith the LORD, your redeemer, the Holy One of Israel; For your sake I have sent to Babylon, and have brought down all their nobles, and the Chaldeans, whose cry is in the ships.
Isaiah 43:15 I am the LORD, your Holy One, the creator of Israel, your King.
The verse centers on "before", "none", "deliver", "hand", and "shall". It is saying that the verse draws attention to "before" and "none", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 12's "I have declared and have saved and..." into verse 14's "Thus saith the LORD your redeemer the...", so "before" and "none" belong inside that flow. In Isaiah context, the local focus is the Holy One of Israel, judgment and restoration, the servant of the LORD, and Zion's hope.
A plain takeaway is to answer the verse's own emphasis on "before" and "none" with trust shaped by these words, not by a vague optimism outside the passage.
