An Invitation to Life
The second half of Isaiah, chapters 40 - 66, is most effusive description of eternal life and the New Heavens and Earth in the entire Bible. It builds in crescendo until the prophecy of the New Creation in Isaiah 65. Isaiah 55 is an invitation to participate in the life promised by the Lord. It is also one of those chapters in Scripture that has a lot of familiar verses.
"Seek the Lord while He may be found. Call upon Him while He is near." verse 6
"For My thoughts are not your thoughts, or My ways your ways," says the Lord. Verse 8
So shall My Word be that goes forth from My mouth. It shall not return to me void." verse 11
"For you shall go out with joy, and be led out with peace. The mountains and hills shall break forth with singing before you, and all the trees shall clap their hands." verse 12
As we read this chapter, right away we know that we are reading a prophecy of the future. "Everyone who thirsts, come to the waters. And you who have no money, come, buy, and eat. Yes, come, buy wine and milk without money and without price." In this sin-stained fallen world, everything is reduced to a price. We have even invented the "dismal science," Economics that makes a special study of the relationship of money and the things that we desire.
The Lord knows that our souls are filled with cravings that we can never fill, but we chase the material desires of our hearts with our limited cash hoping for the merest taste of happiness and real joy. He also knows however difficult it is for us to believe it that he is the real answer. "Incline your ear, and come to Me. Hear and your so shall live."
We must come to the Lord and live in communion with Him.
