“Comfort, comfort my people, says your God.” With these words, Isaiah delivers a beautiful proclamation of hope to a people in exile. In part 5 of a special 12-part series connecting Old Testament prophecy to New Testament fulfillment, we encounter the “Voice” crying in the wilderness. This Voice is St. John the Baptist, the herald who prepares the way for the Lord. He calls sinners to repentance, pointing to the truth that while all flesh is like grass that withers and fades, the Word of our God stands forever, and the Messiah has come.
The Rev. Robert Smith, pastor emeritus in Ft. Wayne, IN, joins the Rev. Dr. Phil Booe to study Isaiah 40:1–11.
This Advent series begins by covering the last Old Testament prophet, Malachi, and then spends twelve episodes alternating between Old Testament prophecy and New Testament fulfillment, tracing God’s promises from Isaiah to the birth of Christ. The series explores Emmanuel’s promise, the Davidic King, John the Baptist as forerunner, and reaches its climax with the Nativity. The final episodes examine the Suffering Servant, the shadow of the cross in Christ’s infancy, Isaiah’s Messianic mission statement, and John’s declaration that “the Word became flesh.”
Thy Strong Word, hosted by Rev. Dr. Phil Booe, pastor of St. John Lutheran Church of Luverne, MN, reveals the light of our salvation in Christ through study of God’s Word, breaking our darkness with His redeeming light. Each weekday, two pastors fix our eyes on Jesus by considering Holy Scripture, verse by verse, in order to be strengthened in the Word and be equipped to faithfully serve in our daily vocations.

Isaiah 40:1-11
Comfort for God’s People
40 Comfort, comfort my people, says your God.
2 Speak tenderly to Jerusalem,
and cry to her
that her warfare[a] is ended,
that her iniquity is pardoned,
that she has received from the Lord‘s hand
double for all her sins.
3 A voice cries:[b]
“In the wilderness prepare the way of the Lord;
make straight in the desert a highway for our God.
4 Every valley shall be lifted up,
and every mountain and hill be made low;
the uneven ground shall become level,
and the rough places a plain.
5 And the glory of the Lord shall be revealed,
and all flesh shall see it together,
for the mouth of the Lord has spoken.”
The Word of God Stands Forever
6 A voice says, “Cry!”
And I said,[c] “What shall I cry?”
All flesh is grass,
and all its beauty[d] is like the flower of the field.
7 The grass withers, the flower fades
when the breath of the Lord blows on it;
surely the people are grass.
8 The grass withers, the flower fades,
but the word of our God will stand forever.
The Greatness of God
9 Go on up to a high mountain,
O Zion, herald of good news;[e]
lift up your voice with strength,
O Jerusalem, herald of good news;[f]
lift it up, fear not;
say to the cities of Judah,
“Behold your God!”
10 Behold, the Lord God comes with might,
and his arm rules for him;
behold, his reward is with him,
and his recompense before him.
11 He will tend his flock like a shepherd;
he will gather the lambs in his arms;
he will carry them in his bosom,
and gently lead those that are with young.
