Believers, he added, must show their belief in their daily lives, so that the world might see the light shining in their faces.
A bright and happy face cheers people on their way.
If you are sad, and pass a child who is laughing, the child, seeing your sad face, will cease to laugh, not knowing why.
If the day be dark, how much a gleam of sunshine is prized;
so let believers wear smiling happy faces, gleaming like sunshine in the darkness.
Let the Light of Truth and Honesty shine from them, so that all who behold them may know that their word in business or pleasure will be a word to trust and depend upon.
~ Abdu’l-Baha, Abdu’l-Baha in London, p. 124
