What significant event took place in the garden of Gethsemane?

The garden of Gethsemane is significant in Christian theology primarily because it is where Jesus experienced intense anguish before his crucifixion and where he was ultimately betrayed by Judas Iscariot. This event marks a crucial moment in the narrative of the Passion, as Jesus prayed fervently, asking for strength to face his impending suffering, while his disciples struggled to stay awake and support him. The betrayal by Judas led to Jesus’ arrest and set in motion the events leading to his crucifixion.

The other options, while they reflect important aspects of Jesus' life and ministry, do not pertain to the specific events that took place in Gethsemane. For instance, Jesus healing the sick and teaching his disciples happened throughout his ministry but not specifically in Gethsemane, and the resurrection occurred three days after his crucifixion, not in the garden. This context highlights the unique and pivotal nature of the events in the garden of Gethsemane, making the revelation of betrayal the defining moment associated with this location.
