In this sermon, the preacher begins by reading from Joshua chapter 24, emphasizing the importance of fearing and serving the Lord in sincerity and truth. He warns against the dangers of humanism, which is the worship of the creature rather than the creator. The preacher also shares a humorous anecdote about Charles Spurgeon, a well-known preacher who used his ministry income to build an orphanage. The sermon concludes with a mention of the preacher's appreciation for the support and condolences received for his mother-in-law, and a reminder to always be grateful to the Lord.
