Isaiah 39 is interesting to me. Were the Babylonian men spies? Did they go back to Babylon and log all the riches they saw in Hezekiah's kingdom for later perusal? Should Hezekiah not have shown them all his riches? The prophecy Isaiah brings against Hezekiah concerns the future - not Hezekiah's time - and Hezekiah is happy with that. Should he have wept for future generations? Was he selfish in this? So many questions...probably not as many answers.
Isaiah 40:8 - "The grass withers, the flower fades, But the word of our God stands forever." This verse is quoted in 1 Peter 1:24-25. Peter goes on to say, "And this is the word which was preached to you." The word of God extends through all space and time, even to the present. Jesus said in Matt. 5, "Do not think that I came to abolish the Law or the prophets. I did not come to abolish but to fulfill. For truly I say to you, until heaven and earth pass away, not the smallest letter or stroke shall pass from the Law until all is fulfilled." Only a word from God can change or annul another word from God.
The end of chapter 40 is incredible. How great is the Lord? The nations of the earth are nothing to Him. He created every star in the heavens.
Isa 40:28-31 "Do you not know? Have you not heard? The Everlasting God, the LORD, the Creator of the ends of the earth Does not become weary or tired. His understanding is inscrutable. He gives strength to the weary, And to him who lacks might He increases power. Though youths grow weary and tired, And vigorous young men stumble badly, Yet those who wait for the LORD Will gain new strength; They will mount up with wings like eagles, They will run and not get tired, They will walk and not become weary."
He gives strength and needs no one to give Him strength. He is the SOURCE of all strength and power. He needs absolutely nothing from any of us. He has no equal anywhere. He is supreme. Praise God for His majesty and might!
