And that, knowing the time, that now it is high time to awake out of sleep: for now, is our salvation nearer than when we believed. The night is far spent, the day is at hand: let us therefore cast off the works of darkness and let us put on the armour of light. Let us walk honestly, as in the day, not in rioting and drunkenness, not in chambering and wantonness, not in strife and envying.
Romans 13:11-13 KJV
The person who has the light ought to be shining. Let your light so shine that men may see your good works and glorify your Father, which is in Heaven.
