When Moses asked God by Who he should tell the Israelite nation had sent him, God replied, “I am who I am.” (Exodus 3:14) This declaration is found over 6,000 times in the Old Testament and is the personal name of God by which He reveals Himself. For within the meaning is the timelessness and very foundation of all existence…by the Maker and Creator of all things. So in this verse in Jeremiah, God is making Himself known in order that we may recognize Him for Who He is…the all powerful, all sufficient, Almighty God.
Earlier in this Chapter, Isaiah speaks of the power and magnificence of God and how there is no other God besides Him. He then addresses the many idols of Israel…man-made pieces that they have put their trust in rather than God. Finally, in these verses above, Isaiah sarcastically suggests they bring their idols to him so they may be questioned about past and future events in order to somehow legitimize their “godliness”. His sarcasm only continues as he urges these idols to, “Do something, don’t just sit there looking at me!” No man-made idol will ever take the place of God, for no man-made idol has the capacity, authority, dominion, or might as God does.
