The sermon explores the nature of faith, contrasting Abel's faith-based offering with Cain's work-driven approach, drawing from Hebrews 11. It emphasizes that true salvation comes through faith, not works, and warns against a modern trend within the church of prioritizing personal preference over sound doctrine. The preacher reflects on the importance of a shepherd's heart, the need for accountability, and the enduring legacy one leaves behind, ultimately urging listeners to ensure their lives reflect faith and obedience so that they may hear the affirming words, 'Well done, thou good and faithful servant,' upon their death.
