We are going to begin this sermon in Isaiah 40, and go through a number of verses here. First of all, just so that you see who this section is addressed to, in verse 9 it says:
Then comes a section that deals with a set of contrasts between this God and other gods which people were worshipping. Also a series of questions are asked in order to stimulate our thinking in regard to the God we worship - and being able to see Him in some of His majesty. We get down to verse 18, and the question is asked:
You might want to write down Isaiah 43:6-12, because God shows us there that we are His witnesses that He is God. That connects directly to the first series of verses I gave you in Isaiah 40, where the church is supposed to say to Judah, Behold your God. And we are His witnesses, that He is God.
