This sermon explores Jesus' teachings in Matthew 6:22-24, focusing on the metaphor of the eye as the lamp of the body. The pastor emphasizes the importance of having a "healthy" or "clear" spiritual vision, which leads to a life full of light. He contrasts this with the darkness that comes from valuing worldly treasures, particularly money, over God. The sermon calls for repentance and a singular focus on God's kingdom, warning against serving two masters and encouraging believers to treasure Christ above all else.
