"between Christ and Satan. Every Christian is to be a light, not hid under a bushel or under a bed, but put on a candlestick, that light may be given to all who are in the house. Never, from cowardice or worldly policy, let the truth of God be placed in the background. 6T 144.2"
"Neither do men light a candle, and put it under a bushel, but on a candlestick; and it giveth light unto all that are in the house."
EGW directly quotes and applies the Matthew 5:15 passage about not hiding one's light.
