What This Free Course Covers

This free course gathers short question-and-answer lessons on difficult sayings in the Sermon on the Mount and related Gospel passages. The lessons focus especially on how early Christians understood Jesus’ words in Matthew 5–7. Students will consider what Jesus meant when He said He came not to destroy the law but to fulfill it, whether “these commandments” refers to His own commands, and why His teachings are treated as binding rather than optional ideals.

The course also addresses practical questions about sharing holy things wisely, not throwing pearls before swine, anger, insults, and the meaning of calling someone “foolish.” The final lessons look at Jesus’ saying about the eye as the lamp of the body, connecting it to the heart’s willingness to receive hard teachings about wealth, possessions, and seeking the kingdom first.

Together, the lessons show how individual sayings fit within the larger moral and spiritual force of the Sermon on the Mount.
