Most people today have their minds set on acquiring much material things and make it big in the world. They spend most of their time and energy in working just to have it all or to be economically better off than their friends and neighbors.
Sometimes, their being busy with such material endeavors leaves them no time for their spiritual needs, which is of paramount importance for a person to have a really meaningful and satisfying life. It's true that material things can do good for our survival, but these cannot give perfect health, extend our lives, keep us away from sickness and accidents, and the likes.
On the other hand, spiritual riches can benefit us in so many ways even while we live in this wicked and suffering-infested world. They can make our lives truly worth-living and satisfying. Most of all, they can lead us to a future filled with all the things that our hearts desire; to a new paradisaic world where all people will be righteous and perfect and will live eternally just as our loving Creator has purposed it to be.
It is therefore more important to work harder on acquiring spiritual riches first, that is, pursuing the will of God and abiding by it, than to acquire material things that cannot save us at all and that will be done away with. That means our future, a future that will last forever.
The Scripture below is worth-meditating on.
"For what benefit will it be to a man if he gains the whole world but forfeits his soul? " - Matthew 16:26
