Vanity has been described in many ways but I would like to use this opportunity to express my view to break this topic into its simplest form. Many preachers and writers have explained it in different ways but I would like to compare it to our Scripture.
Vanity is explained as the quality of being valueless or futile.

According to the scripture, the Book of Ecclesiastes made it clear that everything is vanity. Let's quickly look at how the scriptures explained themselves. The Scripture says, 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 blow to the south, and goes round to the north; round and round 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 is the ear filled with hearing. What has been being 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. There is no remembrance of former things, nor will there be any remembrance of later things yet to happen among those who come after.

The preacher has been king over Israel in Jerusalem. The preacher has applied his mind to seek and to search out by wisdom all that is done under heaven;
It is an unhappy business that God has given to the sons of men to be busy with.

I have seen everything that is done under the sun, and behold, all is vanity and a striving after wind. What is crooked cannot be made straight, and what is lacking cannot be numbered. The preacher said, he has acquired great wisdom, surpassing all who were over Jerusalem before him, and my mind has had great experience of wisdom and knowledge.

Beloved, I believe this article has taught us a lot about everything. Please let us quickly communicate to share out ideas to improve our knowledge of Christ. May the good Lord bless everyone and continue to share his blessing and mercy upon us.
Thanks for being with us.
