Matthew 5:16 (KJV) Let your light so shine before men, that they may see your good works, and glorify your Father which is in heaven.
Your good deed and christ-like character should preach Christ more than your words.
Let your light shine, let your character speak, let your conduct draw men to Jesus.
Your utterance should reflect the one that lives in you.
The nature of God must be seen in the way you handle situations.
Your lifestyle must be a reflection of him.
