John 12:7 'Then said Jesus, Let her alone: against the day of my burying hath she kept this.' The sermon examines the anointing of Jesus by Mary in Bethany, arguing that the accounts in John, Matthew, and Mark describe a single event. It highlights Mary's ministry as sacrificial, humble, and purposeful, contrasting her silent devotion with Judas's hypocritical criticism. The preacher emphasises that Christian service must prioritise spiritual obedience over social responsibilities or public approval. True worship involves setting aside personal glory to honor Christ alone, regardless of external murmuring. Believers are encouraged to serve faithfully by doing what they can for the Lord with a pure heart.
