Light on or off?

"The Christian must be a shining person, who brings light, who always gives light! A light that is not his, but a gift from God, it is Jesus’ gift. And we carry this light. If the Christian extinguishes this light, his life has no meaning. He is a Christian in name only, he does not bring light with him, his light is without meaning. But I would like to ask you now, how do you want to live? Do you want to live like a light that is on or one that is off? On or off? How do you want to live?  A light that is on! It is God himself who gives us this light and we give it to others. A light that is on! This is the Christian vocation.
