Isaiah 40

Comfort for God's People

 1 Comfort, comfort my people,
       says your God.

    2 Speak tenderly to Jerusalem,
       and proclaim to her
       that her hard service has been completed,
       that her sin has been paid for,
       that she has received from the LORD's hand
       double for all her sins.

    3 A voice of one calling:
       "In the wilderness prepare
       the way for the LORD ^[a];
       make straight in the desert
       a highway for our God. ^[b]

    4 Every valley shall be raised up,
       every mountain and hill made low;
       the rough ground shall become level,
       the rugged places a plain.

    5 And the glory of the LORD will be revealed,
       and all people will see it together.
       For the mouth of the LORD has spoken."

    6 A voice says, "Cry out."
       And I said, "What shall I cry?"
       "All people are like grass,
       and all human 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."

    9 You who bring good news to Zion,
       go up on a high mountain.
       You who bring good news to Jerusalem, ^[c]
       lift up your voice with a shout,
       lift it up, do not be afraid;
       say to the towns of Judah,
       "Here is your God!"

    10 See, the Sovereign LORD comes with power,
       and his arm rules for him.
       See, his reward is with him,
       and his recompense accompanies him.

    11 He tends his flock like a shepherd:
       He gathers the lambs in his arms
       and carries them close to his heart;
       he gently leads those that have young.

    12 Who has measured the waters in the hollow of his hand,
       or with the breadth of his hand marked off the heavens?
       Who has held the dust of the earth in a basket,
       or weighed the mountains on the scales
       and the hills in a balance?

    13 Who can fathom the Spirit ^[d] of the LORD,
       or instruct the LORD as his counselor?

    14 Whom did the LORD consult to enlighten him,
       and who taught him the right way?
       Who was it that taught him knowledge,
       or showed him the path of understanding?

    15 Surely the nations are like a drop in a bucket;
       they are regarded as dust on the scales;
       he weighs the islands as though they were fine dust.

    16 Lebanon is not sufficient for altar fires,
       nor its animals enough for burnt offerings.

    17 Before him all the nations are as nothing;
       they are regarded by him as worthless
       and less than nothing.

    18 With whom, then, will you compare God?
       To what image will you liken him?

    19 As for an idol, a metal worker casts it,
       and a goldsmith overlays it with gold
       and fashions silver chains for it.

    20 People too poor to present such an offering
       select wood that will not rot.
       They look for a skilled worker
       to set up an idol that will not topple.

    21 Do you not know?
       Have you not heard?
       Has it not been told you from the beginning?
       Have you not understood since the earth was founded?

    22 He sits enthroned above the circle of the earth,
       and its people are like grasshoppers.
       He stretches out the heavens like a canopy,
       and spreads them out like a tent to live in.

    23 He brings princes to naught
       and reduces the rulers of this world to nothing.

    24 No sooner are they planted,
       no sooner are they sown,
       no sooner do they take root in the ground,
       than he blows on them and they wither,
       and a whirlwind sweeps them away like chaff.

    25 "To whom will you compare me?
       Or who is my equal?" says the Holy One.

    26 Lift up your eyes and look to the heavens:
       Who created all these?
       He who brings out the starry host one by one,
       and calls them each by name.
       Because of his great power and mighty strength,
       not one of them is missing.

    27 Why do you complain, Jacob?
       Why do you say, Israel,
       "My way is hidden from the LORD;
       my cause is disregarded by my God"?

    28 Do you not know?
       Have you not heard?
       The LORD is the everlasting God,
       the Creator of the ends of the earth.
       He will not grow tired or weary,
       and his understanding no one can fathom.

    29 He gives strength to the weary
       and increases the power of the weak.

    30 Even youths grow tired and weary,
       and young men stumble and fall;

    31 but those who hope in the LORD
       will renew their strength.
       They will soar on wings like eagles;
       they will run and not grow weary,
       they will walk and not be faint.

Romans 8:28

And we know that in all things God works for the good of those who love him, who ^[k] have been called according to his purpose. 29 For those God foreknew he also predestined to be conformed to the image of his Son, that he might be the firstborn among many brothers and sisters. 30 And those he predestined, he also called; those he called, he also justified; those he justified, he also glorified.

Also from this study the words of Oswald Chambers (paraphrasing here)- Wherever you are, know that God placed you their to serve His good purpose.  Keep to the light and His purpose will be served.
