We are ambassadors for Christ, since God is making his appeal through us; we entreat you on behalf of Christ, be reconciled to God. (2 Corinthians 5:20)
“The lamp of the body is the eye. If your eye is sound, your whole body will be filled with light; but if your eye is bad, your whole body will be in darkness. And if the light in you is darkness, how great will the darkness be.” Matthew 6:22–23
