Isaiah writes in similar vein as Joel did concerning the wrath of God. Compare Isaiah Chapters 5, 1, and 2 with Joel (especially Joel 2).

"Therefore the Lord's anger burns against his people."

There are consequences for God's people rejecting His command and His Word.  Notice it says, HIS people.  What were the people doing to cause God's anger to burn against them?  Isaiah tells us in chapter 2 verses 19-21.  They were worshiping their silver and gold, just as we today, worship our "gods" of money, possessions, etc.

What did God say would happen to the people of Israel?

"...the LORD Almighty is about to take from Jerusalem and Judah both supply and support; all supplies of food and all supplies of water."

God did that to Israel. Nebuchadnezzar cut off supplies of food and water from the people who had taken refuge in the city of Jerusalem.  He will do that to us if we continue in our wicked ways.  This can happen if an EMP (electromagnetic pulse -from the sun)hits America today.  Time is short and getting shorter.

"Come now, let us reason together," says the LORD.

Indeed, let us reason together.  He tells us in His Word to follow His commands and to turn away from other "gods" and back to Him. Repent, so that times of refreshing may come.  We can read about times of refreshing in Isaiah 4 and Isaiah 2. This is how things will look in the Millennial Kingdom. 

"Come, O house of Jacob, let us walk in the light of the LORD."

Come, O believers in Jesus, let us walk in His light."

Oh, what an unbelievably compelling ending to today’s reading. The imagery is incredible! Isaiah was allowed to see the throne of the Lord in the heavenly temple. Isaiah knew he was in the presence of the Lord and he knew he was unworthy. He lamented, “Woe to me!” and “…my eyes have seen the King, the Lord Almighty.”

He no doubt was very familiar with this Scripture:
Exodus 33:20
But,” he said, “you cannot see my face, for no one may see me and live.”

Isaiah knew he would not be able to look upon the face of God and live. But he wasn’t looking upon the face of God, the Father. John identified the glory that Isaiah saw. He saw God, the Son!

John 12:41
Isaiah said this because he saw Jesus' glory and spoke about him.

I (Patti) have always been drawn to the verse, “Here am I. Send me!” As a teen-age Christian I thought God was speaking to me about being a missionary. Some 45 years later I have come to understand just what being a missionary really means.

Contrast Isaiah's response to God's question to Moses' response to a similar question.  Isaiah responded immediately with the answer God wanted to hear.  Moses tossed out excuses.

Did you attach yourselves to the oxygen tank as we have been deep-sea diving in Isaiah?

One final note on today’s reading.
2 Chr 27:6
Jotham grew powerful because he walked steadfastly before the LORD his God.

Jotham lined up his will with God’s will. Pretty good advice for us today!
