Sermon on the Mount: Healthy Eyes

Jesus teaches in Matthew 6:19-24 that having "healthy eyes" means cultivating both generosity and single-mindedness in our spiritual vision. Just as we can't physically focus on two things at once, we cannot serve both God and material possessions - we must choose whether our eyes will be full of light (focused on eternal things) or darkness (focused on earthly treasures). The sermon emphasizes that when we seek first God's Kingdom with healthy spiritual vision, maintaining a generous heart and undivided focus on heavenly things, God will provide everything we need.
