What you focus on shapes everything about how you live. Jesus, in Matthew 6, teaches that a healthy eye is one that is undivided and fully fixed on Him, and when that is true, life is filled with light, wisdom, and clarity. An unhealthy eye, what the original Greek calls the evil eye, is one corrupted by greed, covetousness, and a desire to possess and control. When our gaze drifts from Jesus, we begin to see people as competition, generosity as loss, and obedience as risk. Perhaps the most sobering warning is that some people believe they are walking in light while actually living in deep darkness, going through religious motions without genuine surrender. The answer is not more religious activity but a complete turning of our eyes to Jesus. When we fix our gaze on the One who gave up everything out of love for us, the world comes into its proper perspective. That is what it means to truly live in the light.
