God called him a fool, because anyone whose decisions about the present do not take into consideration the possibilities of the future is indeed a fool. He was also foolish because he thought that riches, possessions, and achievements were everything. He forgot that a moment after death the millionaire is no richer than the beggar. He needed to bank more eternal and spiritual riches, for character is what a person is before God when they are stripped of their possessions. The most important and valuable pursuit of life is to make thorough preparation for the eternal kingdom of God.
Eternal life is singularly the most important pursuit of life.
And eternal life is only possible as a consequence of knowing Jesus Christ as our personal Saviour. In Psalms 73 the psalmist laments the fact that those who serve God always seem to be poor, they are the ones who suffer a great deal, and even in their death they suffer. But then he realizes that true happiness is not derived from having and owning riches. I was as stupid as an animal. You are always with me and that's all that matters. .
