Matthew 5:16 ASV

Letting our light shine in front of other men and women is the demonstration of the seed inside of us. Our good works, not the a loud message we shout is what will glorify the Father in heaven. Imagine a man who speaks all he can of the gospel, but doesn't drop a penny in a poor person's cup, what good is their mouth if their heart doesn't follow. But imagine a man who's lips are sealed, but who's heart is full of generosity to those in need and those not. His heart can life still point to the life of His father in heaven and his heart.
