In this passage found in the Gospels of Matthew and Luke, Jesus speaks about the light of the body. He emphasizes the importance of letting one's light shine so that others may see the good works of God. Jesus uses the metaphor of the eye as the lamp of the body, indicating that if one's eye is healthy and focused on godly things, their whole body will be filled with light. However, if one's eye is unhealthy and focused on worldly desires, their body will be filled with darkness.

Both Matthew 5:15 and Luke 11:33-36 convey a similar message about the significance of being a light to the world through one's actions and intentions. The passage is important as it reminds Christians to live in a way that reflects the love and goodness of God, impacting those around them positively. A practical application for readers is to daily reflect on their attitudes and actions, making sure they are aligned with God's will and shining brightly for others to see.

The passage is not found in other parts of the gospels.
