Isaiah 44:6-8. “Thus saith the Lord, the King of Israel, and his Redeemer the Lord of hosts: I am the First, and I am the Last: and beside me there is no god. And who, as I, shall call, and shall declare it, and set it in order for Me, since I appointed the ancient people? and the things that are coming, and shall come, let them shew unto them. Fear ye not, neither be afraid: have not I told thee from that time, and have declared it? ye are even my witnesses. Is there a God beside me? yea, there is no God; I know not any.”
Here, God clarifies to His people that there is NO OTHER GOD but Him. They persist in turning to the idols worshiped by the surrounding nations, forgetting that He is the Creator and King, Redeemer, First, Last, and only One Who is worthy of praise.
In verse 7, He declares Himself to be the only One Who can call or command events to happen, to declare them before they happen, and to decide their time and order of fulfillment. He also made it clear that He had been revealing this to Israel from the time He chose and appointed them as His witnesses.
God’s question in verse 8, Is there a god beside Me? is followed by His simple answer: Yea, there is no god. I know not any.
If God, Who is all-knowing, knows of no other gods, then there simply aren’t any. If there were, He would know.
Truth is so often simpler than the lies that man devises.
