Anthony Gammage – Ecclesiastes 1:3-11
What does man gain by all the toil at which he toils under the sun? A generation goes, and a generation comes, but the earth remains forever.
The sun rises, and the sun goes down, and hastens to the place where it rises. The wind blows to the south and goes around to the north; around and around goes the wind, and on its circuits the wind returns. All streams run to the sea, but the sea is not full; to the place where the streams flow, there they flow again. All things are full of weariness; a man cannot utter it; the eye is not satisfied with seeing, nor the ear filled with hearing. What has been is what will be, and what has been done is what will be done, and there is nothing new under the sun. Is there a thing of which it is said, “See, this is new”? It has been already in the ages before us.
Ecclesiastes 1:11  There is no remembrance of former things, nor will there be any remembrance of later things yet to be among those who come after.
From the rising of the sun to its setting, the name of the LORD is to be praised!
He lays the beams of his chambers on the waters; he makes the clouds his chariot; he rides on the wings of the wind; he makes his messengers winds, his ministers a flaming fire.
The steadfast love of the LORD never ceases; his mercies never come to an end; they are new every morning; great is your faithfulness. “The LORD is my portion,” says my soul, “therefore I will hope in him.”
You have kept count of my tossings; put my tears in your bottle. Are they not in your book?
And he who was seated on the throne said, “Behold, I am making all things new.” Also he said, “Write this down, for these words are trustworthy and true.” And he said to me, “It is done! I am the Alpha and the Omega, the beginning and the end. To the thirsty I will give from the spring of the water of life without payment. The one who conquers will have this heritage, and I will be his God and he will be my son.
When we finally say, “why bother?” The answer is that we have a Savior who looked at all the futility and frustration we suffer in this fallen world and chose to suffer it with us and for us so He could actually do something about it.
