During this Season of Hope, we are studying texts related to the Advent, or coming of the fulfillment of God’s promises in the Messiah. Just like ancient Israel had to wait for his coming, we too wait for his second coming.
Isaiah 40 makes reference to this time of waiting.
6 A voice says, “Cry out.”Isaiah 40:6–8 NIV
And I said, “What shall I cry?”
“All people are like grass,
and all their faithfulness is like the flowers of the field.
7 The grass withers and the flowers fall,
because the breath of the Lord blows on them.
Surely the people are grass.
8 The grass withers and the flowers fall,
but the word of our God endures forever.”
In these verses we have a heavenly voice (the speaker is unclear, perhaps Yahweh, an angel, or some other heavenly being) telling Isaiah that humans are like grass and their works like flowers. What the voice is reminding us is that grass and flowers are only around for a season before they wither and fade away. They do not last forever. But the word of God does indeed last forever.
Let’s put this in the context of Israel coming out of exile. They have been away from their homes for a generation, and there is this promise of return. God will make the path easy, he will restore Jerusalem, he will keep his promises. His word will not fail! But humans don’t live forever. We all die. God’s promises, however, do not die.
Isaiah is trying to remind us that we may wait for God to fulfill his promises, and they may not be fully fulfilled in our lifetime before we “wither.” Isaiah wants us to remember that our waiting does not negate God’s promises. Even if we never see them fulfilled, we can rest assured that they will be fulfilled because God’s word endures forever.
Centuries after this text was written, one would come as “a voice of one calling: In the wilderness prepare the way for the LORD.” (Isa. 40:3, Mark 1:3). Mark, as well as the other Gospel writers, want us to realize that God kept this promise fully in the ministry of John the Baptist, “and the glory of the LORD” was revealed in the Advent of Jesus (Isa. 40:5).
Though Isaiah’s words to exiled Israel were not fully realized in their lifetime, God fulfilled his promise through the Advent of Jesus. And though God’s kingdom has not fully come, we can rest assured that God will fulfill his promises through the Advent of Jesus.
