Vanity of vanities, says the Preacher, vanity of vanities! All is vanity. What does man gain by all the toil at which he toils under the sun?
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.
I have seen everything that is done under the sun, and behold, all is vanity and a striving after wind.
For the Gentiles seek after all these things, and your heavenly Father knows that you need them all. But seek first the kingdom of God and his righteousness, and all these things will be added to you.1 Corinthians 15:58
Therefore, my beloved brothers, be steadfast, immovable, always abounding in the work of the Lord, knowing that in the Lord your labor is not in vain.
