In this sermon, the preacher discusses a parable told by Jesus about a prosperous farmer who had a bumper harvest. The farmer's success led him to believe that he was secure and could enjoy a comfortable retirement. However, God spoke to him and called him a fool, reminding him that his life could be demanded from him at any moment. The preacher emphasizes that no amount of wealth or possessions can provide true security in the face of death and judgment. The sermon serves as a warning to prioritize being rich toward God rather than storing up earthly treasures.
