The Lord stands up for His people in 41. He also makes sure to clarify that He is the only Lord. No idols can compare.
My wife really likes 41:10. She has good taste.
The Lord’s chosen servant is described in chapter 42. He is going to do some BIG things.
Now listen to this one, from chapter 43: “I, I am he who blots out your transgressions for my own sake, and I will not remember your sins.” For His own sake, He blots out, wipes out, does away with our transgressions. He won’t remember our sins. Praise Him!
