Jesus warns us against living a foolish life:
"Take care, and be on your guard against all covetousness, for one’s life does not consist in the abundance of his possessions.” And he told them a parable, saying, “The land of a rich man produced plentifully, and he thought to himself, ‘What shall I do, for I have nowhere to store my crops?’ And he said, ‘I will do this: I will tear down my barns and build larger ones, and there I will store all my grain and my goods.’ And I will say to my soul, ‘Soul, you have ample goods laid up for many years; relax, eat, drink, be merry.’ But God said to him, ‘Fool! This night your soul is required of you, and the things you have prepared, whose will they be?’ So is the one who lays up treasure for himself and is not rich toward God.” (Luke 12:15-21)
The fool didn't commit any major crime. He just wanted to sit on his pile. What then is the essence of the unfoolish life? It is a life lived to magnify Jesus Christ.
"It is my eager expectation and hope that I will not be at all ashamed, but that with full courage now as always Christ will be honored [magnified, made to look great] in my body, whether by life or by death. For to me to live is Christ, and to die is gain." (Philippians 1:20-21)
You and I are on this planet for only a few years, all for the same ultimate reason but in various forms. This reason is that we would live and die to make Jesus Christ look as valuable as He really is.
When the Apostle Paul says that to die is gain, he means that Christ is more valuable than anything this world can offer. It’s like what the psalmist said in Psalm 63:3: “Your steadfast love is better than life.”
The key question then becomes, How can I use my possessions and body and time and career, etc. to show that Christ is precious beyond everything?
We are to magnify
Christ, not like how a microscope magnifies things, but like how a telescope magnifies things. Microscopes make tiny things look big; but telescopes reveal seemingly small things to be what they really are: Incredibly Huge!
We exist to display the majesty of Christ because Jesus Christ is God. The universe exists to make Christ known. That’s why God made it. And we have been called to join Him in His self-glorification. [more]
