Pastor Keith discusses the story of Cain and Abel from Genesis 4, focusing on the differing motivations behind their offerings to God. Abel offers his sacrifice in faith and worship, while Cain’s offering stems from self-righteousness and identity in his achievements. When God regards Abel’s offering over Cain’s, Cain becomes angry. God approaches Cain, offering him a chance to correct his heart. Pastor Keith emphasizes true worship as coming to God in humility, seeking grace, and not through self-sufficiency. He invites the congregation to embrace grace, receive communion, and truly worship from the heart.
