You are the light of the world--like a city on a hilltop that cannot be hidden.
No one lights a lamp and then puts in under a basket.
Instead, a lamp is placed on a stand, where it gives light to everyone in the house.
I remember, in my junior-high days, my Sunday school teacher asked us,
"What temperature do you think you should be for Jesus? Cold, lukewarm, or hot?"
Everyone knew the answer wasn't 'cold'. 'Lukewarm', however, sounded comfortable.
"Yeah, lukewarm," we answered.
"Wrong," she said, "you're supposed to be on fire for God."
