This sermon represents Week 15 of a series Darrell taught on the Sermon on the Mount in 1995 at Glendale Presbyterian Church in California. In this message, Darrell explores Jesus’ challenging words in Matthew 5:33–37, where simple honesty replaces oath-making. He shows how Jesus exposes the power of the lie, revealing that oaths exist because of evil and distrust, and how “yes, yes, no, no” breaks evil’s hold. This sermon invites us into a gospel-shaped way of life marked by integrity, faithfulness, and trust in the God who always keeps His promises.
