Isaiah is an Old Testament prophet. While he lived and wrote in a specific time period, God knew what his plan was all along. He revealed his plan to humanity over a period of time. Isaiah didn’t have a full picture but it was clear even by his time, 800 – 900 years before Christ, that God would be doing something new.
*I read Isaiah 1:12-17 and said that I would come back to verse 18. We did do that on Sunday evening but take a look at verse 18 and consider how the sermon points apply.
