Philippians 2:15

A Christian man should so shine in his life, that a person could not live with him a week without knowing the gospel. His conversation should be such that all who are about him should clearly perceive whose he is, and whom he serves; and should see the image of Jesus reflected in his daily actions. A Christian ought to be a comforter, with kind words on his lips, and sympathy in his heart; he should carry sunshine wherever he goes, and diffuse happiness around him.

Spurgeon
