"In the same way, let your light shine before others, that they may see your good deeds and glorify your Father in heaven"- Matthew 5:16 (NIV).
There is a motion sensor in my office and I've found that if I sit still for long, the light goes out, not coming back on until I move. I could sit still for hours and remain in the dark. That's useful in saving energy, but in the world of sharing the Gospel, being still, keeping the light from shining, is counter productive to the Lord's commands. You aren't "saving" anything if your light is not shining. I pass a house each day that recently had a team of people building an extension onto the front porch. They had a sign posted outside: The Jerusalem Project. These people were God's hands and feet. They were a light shining for others to see. Even now, I can't help but look at the new addition each time I pass by and think about what God has done for that family. I personally know the woman is a widow. This story begs me to ask if I've been sitting in darkness, my light not shining, because my motion sensor hasn't detected any movement in a long time. We are the light of the world (Matthew 5:14), designed to bring glory to our Father. The Lord is in the "saving" business: "For this is what the Lord has commanded us: "'I have made you a light for the Gentiles, that you may bring salvation to the ends of the earth'" (Acts 13:47). Oh, that we really had a motion sensor to remind us to move.
