Some small things can be very powerful. There are many insects called ticks in the area where I live. Some ticks are only the size of a pin head, but they can cause serious problems for people and animals. Some ticks carry Lyme disease. People who have Lyme disease may experience painful symptoms for many years.
You may think that you are small and unimportant in the world. But if you are a Christian, you can be a powerful witness for God. Our Bible verses today talk about a light shining in a house. This light helps everyone in the house see so that they don’t stumble and fall in the darkness. In the same way, Christians can be a “light” for people who are living in the darkness of sin. Everything they do should show others God’s love and His plan of salvation.
How can you be a “light” today? Live so that other people “will see the good things you do and praise your Father in heaven” (verse 16b).
