The fool!
“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.” (Luke 12:18)
Jesus told the story of a rich man who had obtained much wealth. But, instead of using it to help others, or to serve God, he had selfish plans!
“And I’ll say to myself, “You have plenty of grain laid up for many years. Take life easy; eat, drink and be merry.”’ (Luke 12:19)
It’s foolish to be selfish!
“But God said to him, ‘You fool! This very night your life will be demanded from you. Then who will get what you have prepared for yourself?’” (Luke 13:20)
In other words,
You never know how long you will live in this world. And once you die, what you attained will no longer be yours to do anything with; it will be out of your control and wasted.
Therefore
“Do nothing from selfish ambition or conceit, but in humility count others more significant than yourselves. Let each of you look not only to his own interests, but also to the interests of others.” (Phil. 2:3-4 ESV)
“Do not lay up for yourselves treasures on earth, where moth and rust destroy and where thieves break in and steal, but lay up for yourselves treasures in heaven, where neither moth nor rust destroys and where thieves do not break in and steal. For where your treasure is, there your heart will be also.” (Matt. 6:18-21)
